Three-Point Turns

One of the basic things you learn during driver’s ed is how to make a 3-point turn.

I have a problem with the 3-point turn.

Not doing the turn – the problem is with the name.

First off, here is a little video is made showing how a 3-point turn works. I did an cursory internet search for an animated diagram of 3-point turn, but didn’t find any. So I made one myself. It is not a very polished animation, because I drew the frames individually and pieced them together. I bet the better-looking videos out there use animation-rendering software, which I don’t have because I’m not planning on doing much animation.

Now, having watched the video, you can see my problem with the name. Specifically, the number given to the maneuver.
Point #1 is obvious – it’s where the car stops and reverses direction.
Point #2 is also obvious – it’s where the car stops and reverses direction again.
Point #3 – I just made it up. I had to put a third point in there somewhere to make it a 3-point turn, but there is no place it fits.

Where is the third point in a 3-point turn?
