Odd then, how I manage to see (and participate in) the zipper merge every single day. Maybe you’re living in a parallel universe? Which one of us has a goatee?

when the signal goes green for stopped traffic, why do they each start driving one at a time, instead of simultaneously
Because the first guy takes his foot off the brake and pushes the gas a fraction of a second after the light changes, then the next guy back takes his foot off the brake and pushes the gas a fraction of a second after he sees the car ahead of him start to move [since he doesn’t want to run into that guy], and so on down the line. If they all started to move at the very same time, there’d be a bunch of cars running into each other, since they’re all unpredictable humans.
This is a situation where robot drivers would excel. Ten cars sitting in a row at the light; they all get the simultaneous “Go” signal, and can all start moving immediately.
That’s a quote from my post. The context was that I was saying that people could simply coordinate their manoeuvres with what they have, and it would be easier than sinking billions of dollars into making cars that do it instead. I don’t think it would be easy, but it’s not like any effort, money, or initiative has ever actually been put into getting people to synchronize their driving.
