good thread a tangent: it is very hard to keep "ownership" of a 5 carlength gap ahead of one in traffic. "you're not using that!" is the ethic. And thus a safety margin is eroded so that some idiot can get 25 feet closer to his destination.https://twitter.com/drethelin/status/1120743461282512897 …
yep, agree with that.
And if we stacked the cars bumper-to-bumper and accelerated smoothly bc it's all under computer control, we'd maximize throughput.
but beyond a certain density, when actual humans are driving, average speed falls.
30% density @ 60mph > 50% density @30 mph

plus, we also care about latency, not pure throughput

Platooning is a compromise between density and fault tolerance. https://en.m.wikipedia.org/wiki/Platoon_(automobile) …
