Turn into the Spin

With a nice variety of winter weather lately, combined with a teenager with a new-ish driving permit, we as a family had some discussions during his drive in snow.

The phrase that came up was “turn into the spin”. That was an answer to what you’re supposed to do if you start to lose control of the vehicle.

The main problem with that phrase is that it is ambiguous. People have different ideas of which direction that is. Is that with the spin, or against the spin?

I told my new driver to forget that phrase and just point the wheels in the direction you want the car to go.

The other problem with that phrase is that it is a phrase. It won’t help you in an emergency because you need to think about it. The best way to prepare for an emergency is to practice it. So he’s going to practice it. Don’t worry, it’s a class given by professionals. But then his mind will know what to do.

You indeed put them on slippery ground; You dropped them into ruin.

Roundabout Signals

Twice this last week, I noticed people signalling right-turn as they entered a roundabout that I also was approaching. Then they didn’t turn right but rather went straight through the roundabout (following the lane, of course).

That is one of the things that bugs me. Apparently some people are being taught to signal right when you’re entering a roundabout, and then signal again when you’re exiting a roundabout.

I don’t mind the signalling when exiting a roundabout, but it’s the “signal right when entering a roundabout” that’s the problem. These people are considering the road meeting the roundabout as an intersection. I consider the whole roundabout the intersection.

Here’s how I see it.

First up, a generic intersection :

image of a generic intersection, 4-way, no controls

This one doesn’t have any controls, so it’s at a high risk of people crashing. We need some way to coordinate who has the right of way. So we could make it a 4-way stop :

image of a generic intersection, 4-way, stop sign

That’s better. Now if you were approaching this intersection and wanted to turn left, you would signal left and you approach it, and the car would cancel the signal after the turn was completed.

Everyone agree? Ok, now we’re going to change the traffic control method from stop signs to a traffic light :

image of a generic intersection, 4-way, stop light

Does that change anything if you want to turn left? I hope not. You would activate your left turn signal as you approached the intersection, and the car would cancel the signal after the turn was completed.

In each case, the control method inside the dashed box doesn’t matter. You have options for the intersection, so you signal as you approach the box to let people know which leg of the intersection you’ll be taking.

Now let’s replace the stop light with a roundabout :

image of a generic intersection, 4-way, roundabout

I’m stating that it doesn’t change anything – you should signal left and you approach the intersection, and the car would cancel the signal after the turn was completed.

The problem with signalling right to enter the intersection is that people on the other legs of roundabout can’t tell the difference between that and signalling to take the first roundabout exit. It’s a bad idea.

It doesn’t add any information to the situation. The reason for signalling at intersections is to add information to the situation so that other drivers can make better decisions.

When entering a roundabout, everyone has to do the same thing – a slight right curve. Turn signals are to inform other people that you’re going to deviate from the current path, or to let them know which option you’re choosing when there are multiple options. When entering a roundabout, there are no multiple options (that’s one of the benefits of roundabouts) and you’re not deviating from a path. The path deviation should come when you exit, not enter a roundabout.

So the turn signal doesn’t add any information that’s needed. But it’s worse than that – it adds bad information. It causes confusion and delay, and that’s the worst thing that could happen, both here and on Sodor.

One caveat is that this is for roundabouts, not traffic circles. And it seems to me that whoever is teaching the signal right whenever entering a roundabout is someone who grew up with a traffic circle. Because those aren’t one intersection – they are big and are individual intersections around a circle.

Who winks with his eyes, who signals with his feet, Who points with his fingers

Zipper Merge

I was driving yesterday on a freeway that I’m familiar with but haven’t driven in a while. The traffic report said there was a slowdown, so I knew to be ready for that.

Sure enough, there were some brake lights and both lanes slowed. The orange construction sign said “Left lane closed ahead – 2 miles”. I was in the left lane, so I decided to stay in the left lane and see if I could promote the zipper merge.

I stayed in the left lane. The next sign said “Left lane closed ahead – 1 mile”. Stayed in the left lane still. “Left lane closed ahead – 1/2 mile”. Still stayed.

Then the next sign (about T minus 1/4 mile) said to merge. It had no text, so I can’t type what it said, but it was the two lines getting closer picture. So I merged at that point, because that’s when the people setting up the construction zone said to merge.

There were people who merged into the right lane back when the first sign said “left lane closed ahead”. And people merged after that too.

And then there were people who didn’t merge when I did – they kept going in the left lane. And I wondered when they were going to merge. The 1/4 mile came and went, and there was no lane closure. Both lanes stayed open – there weren’t even any barrels set out on the side of the road.

Then I realized one of the benefits of waiting until the merge point to zipper merge, rather than merging at the first sign of an upcoming lane closure: if the lane isn’t actually closed, then you don’t cause unnecessary traffic slowdowns by filling up only one lane.

I wish I could have seen around the larger vehicle in front of me to see the lane never closed, before I merged right.

Please let us pass through your land. We will not pass through field or vineyard; we will not even drink water from a well. We will go along the king’s road, not turning to the right or left, until we pass through your territory.

Cars and Temperatures

With some hot temperatures around here recently, I got to thinking about what people think is hot compared to what a car thinks is hot.

Actually the thought process started years ago during a trip to the Badlands. As the temperature was well over 100 (note all temperatures here will be in F not C), I was worried about the car. I knew I would be unhappy being in the sun (no shade in sight, and you can see a long way in that area of the country) with the temp being 105. And I wondered if the minivan was equally unhappy.

It’s easy to tell in general, because cars have a temperature gauge. As long as the needle stays in the middle of the gauge, everything is happy. But I have also learned that if the needle starts leaving the good zone, something is bad and it’s too late to do much about it other than turn off the engine.

But I’ve since realized that what we think are hot temperatures are not hot to the car. It was replacing a thermostat and radiator that helped me understand that. The thermostat was rated for 195 – that’s the normal operating temperature of the engine coolant.

My body’s thermostat, however, is around 98.6 degrees, about half that of the car. So although I’m in danger of overheating in 105 degree weather, the car is not. Going from 80 to 100 degrees is significant to people, but to a car that would feel like going from 40 to 50 degrees to us.

It’s like dog years – a car degree is half a people degree.

Recalling my thermodynamics class back in college: heat moves from the hotter object to the cooler object, like water flowing from a higher point to a lower point. Once the air gets above 98.6-ish, I’m not longer giving off heat, I’m absorbing it. But for a vehicle, that point is 195. And if the air temperature is even close to that we have bigger problems.

And when the sun came up God designated a scorching east wind, and the sun beat down on Jonah’s head so that he became faint, and he begged with all his soul to die, saying, “Death is better to me than life!”

Car Repair Mistakes

I wish I would have started working on cars earlier in life – it would have saved me a bunch of money. Here are some things I’ve learned over the last few years of working on my own cars.

  • When replacing suspension components that involve removing sway bar links, plan ahead and get new sway bar links. This tip does not apply to places where cars don’t get rusty. But around here, sway bar links are considered single-use. They are designed to be able to be removed and re-installed, but that’s only in a perfect world. They’re cheap enough that it’s not worth my time to try to save them. I’ll give it one attempt to undo them, but if they don’t cooperate I just get out the angle grinder and off they go.
  • Speaking of sway bar links (and other stubborn rusty connectors), a good tool to have is an impact wrench. It doesn’t loosen everything, but it has helped. And it helps tighten those sway bar links. I got a cheap electric one from Harbor Freight. I went with corded electric because I don’t have shop air and I don’t use it enough to make it worth managing batteries.
  • The steering wheel on the van was wobbling. Slowly at low speeds and faster at higher speeds. That seemed like an easy diagnosis – one of the front tires broke a belt and is now out of round. So I swapped out the front tires (normal to winter or vice-versa) but the problem continued. I took it to the shop and told them what happened. It didn’t take them long looking at it to find it was a rear tire with the broken belt. Moral of the story: just because the symptom is in the steering wheel doesn’t mean the problem is in the front end.

The workmanship of the wheels was like the workmanship of a chariot wheel. Their axles, their rims, their spokes, and their hubs were all cast.

Buick Lesabre Postmortem

The Buick didn’t quite die, but I pre-emptively sold it to the junkyard. It was a better deal than donating it to charity – if you ever need to get rid of a car, I recommend Wheelzy. I didn’t know it was Wheelzy at first, because it was masquerading as something like Sell Junk Car Lansing dotcom. So many shell sites and phone numbers with any of these junk car places that pretend to be local. But they had the most thorough customer service – between emails and texts there was no way I could not know where I was in the process. But this is supposed to be about the car, not the junkyard.

It was a 2001 Buick Lesabre Custom. I bought it in 2016 with 110,000 miles. It needed a new battery and rear air shocks and front brake pads right away.

The air shocks ended up being bad again in 2020, so I am not a fan of air shocks. If I get a GM car from a similar era, I’ll convert the air shocks to traditional coils rather than fix the air shocks.

Here’s what else needed to go into/onto the Buick to keep it working:
Miles : Item
2016
111k : front engine mount
112k : fuel filter and fuel pressure regulator (cheap, DIY)
113k : fuel pump (not cheap, at shop, before this the engine wouldn’t start if it was warmed up)
116k : new transmission fluid and filter (cheap, DIY, actually made a noticeable difference)
2017
118k : left low beam bulb
120k : right front window regulator ($50, DIY, took a while for this first one)
121k : tie rods, ball joints, and sway bar links (if your wheels make a click when you stop, check your ball joints)
121k : lower intake manifold gasket and valve gasket (emergency repair at shop, $$$)
122k : front struts (dirt roads wear them out)
126k : new thermostat (it was late fall and the engine took forever to get up to temperature, meaning no heat for me)
2018
127k : right low beam bulb
127k : new spark plugs
128k : brake fluid flush (DIY, probably not too thorough but better than nothing)
129k : front rotors
132k : left front window regulator (DIY, about 30 minutes this time
133k : rear brake pads
2019
135k : replace brake tubes (was leaking fluid, all but LF tube were rusted through at some point)
136k : recharge AC
136k : replace alternator (DIY, this is ridiculously easy on this vehicle)
137k : replace one bad ignition coil
137k : replace Ignition Control Module ($40 from junkyard off Ebay, no programming needed)
137k : high beam bulbs (got pulled over and notified one high beam was out, decided to do both at once)
140k : whole new left headlight assembly (necessary because a little old lady misjudged her turning angle in a parking lot)
2020
145k : front brake pads
147k : new wipers
2021
150k : RIP

The steering started getting very loose, it turned out to be a broken rear track bar. But before I replaced that, the right front wheel liner fell off while I was driving. It was caught in something, so I didn’t lose it. When I went to reattach it, I saw the attachment point didn’t exist anymore – it had rusted away.

I had known the bottom of the car was getting rusty, so in the back of my mind I was already starting to weigh the worth of making repairs anymore. Then I couldn’t fix the wheel liner, and when I jacked up the back to look at the track bars something else shifted/broke in the suspension and I knew it was a lost cause.

The car was running fine, it had a lot of good parts. But the body was rusting away so the parts weren’t going to be held together much longer.

Therefore, this is what the Lord God says: “Woe to the bloody city, To the pot in which there is rust And whose rust has not gone out of it! Take out of it piece after piece, Without making a choice.”

Ezekiel 24:6

Of Accidents and Crashes

I kind of got mugged the other night. It was in a store parking lot. I was sitting there, minding my own business, when a little old lady with a handicap tag hanging from her mirror accosted me and forced me to pay $60.

That is, in effect, what happened. What happened, in fact, was that she drove her car into mine and caused about $60 worth of damage to my car. End result is the same though, albeit with less personal danger and more work after the fact.

Here’s the story: I was pulling into the Meijer parking lot and the entering traffic (me) does not have a stop sign, whereas the cross traffic (little old lady, or LOL for short) does. She is going to turn left to leave the parking lot, and starts to do so in front of me. I’m going slow, as I’m anticipating the cross traffic not realizing I don’t have a stop sign, so I’m able to stop before getting to the lady. Note that I wanted to turn right, so I wouldn’t have crossed her path anyway.

So why did I stop instead of turning right? Because she was taking up more than her lane and I didn’t think I had enough room to get through until she left.

But while I’m stopped, waiting for her to complete her turn, she keeps getting closer. I have my foot firmly on the brake, wondering why the gap between us is closing. Then there is a scraping, crunching sound, and I’m wondering why she isn’t stopping, because I can’t go anywhere. Finally she stops and so do the sounds.

Now I notice there’s a truck behind me, so she pulls up to the far curb, and I go around the curb and park in the closest spot. I get out, notice that my bumper is crunched up but the lights seem to still work, then I walk over to her car. She tries to open the door but her sheet metal is deformed just enough that she can’t budge it.

If you want more details of the story you can ask me later, but the end of the story is that since it happened on private property we are free to exchange information and go our separate ways. Since all I got out of it was a dented bumper and a cracked headlight housing, I was glad for that. I ordered the $60 replacement housing and will try to undent the plastic bumper somewhat, but I’m sure the long-term effect will be a slightly uglier vehicle.

Her car, on the other hand, scraped the paint off three separate body panels (front quarter panel, driver door, rear door) and deformed them enough to effect the door hinge operation. Her three seconds of inattention cost her thousands of dollars of damage.

And I must take this time to reflect on my previous accident, less than a year ago. This was on a snowy road. I was on the main road and did not have a stop sign, and the lady (middle-aged lady, or MAL for short) on the side road and who did have a stop sign had trouble stopping and slid into the intersection, right in front of my vehicle. She tried to accelerate and I tried to stop, but it was too close and I ended up bumping her. That bump caused her to go into the ditch, which caused her airbags to go off. All I got out of it was a cracked bumper and cracked headlight housing, so I was glad for that.

Her car, on the other hand, had the airbags go off and required a tow out of the ditch, with police oversight. Her three seconds of late braking cost her thousands of dollars of damage.

On one hand, I hope not to be in anymore car crashes. One the other hand, if I am in a crash I hope it keeps up the trend of not costing me any more than some tens of dollars and a half hour to replace a headlight housing.

When he raises himself up, the mighty fear; Because of the crashing they are bewildered.
