Because no one read it the first time! You jerks!
I'm just gonna post a link to the post that I want to rerun. So go back in time and enjoy a boring post that only a nerd could enjoy. If you're a nerd, of course. Actually, it's mostly a video.
It's funny, because when I wrote Drivers I ended up using that interface that you see in the video, (minus the swaths of red that indicate obstacles.) The drivers see a yellow path to mark where they're going. Nice, eh? But that's only on autopilot, when the computer is driving. When they're driving, there's nothing.
Kind of like life.
