Or I would at least. Because people ahead speed up and slow down, and I couldn't take matching their motions exactly.
Also if you watch, the "stops" in stop and go traffic seem to get started because someone tried to do a lane change too late. They stopped, then people stop behind them, and you get a wave going backwards. Having everyone match the car in front of you wouldn't help with that.
But I would like it if the rule wasn't "constant distance" but rather "distance depending on speed". That would smooth things out.
Cheers,
Ben
