While this is theoretically a reasonable answer (best for AI drivers driving autonomously at 100MPH with humans asleep in the backseat), itâ(TM)s not a realistic one today with mostly impatient fallible meatsacks behind the wheel driving at the speed of greed, enhanced by prescription meds.
It does actually work. Any law not enforced ceases to become a law, so yeah it needs enforcement. It's like, no one speeds on the 84/285 through northern NM, because. well you're going to get a ticket from a reservation cop. You can try challenging it in a reservation court with a reservation judge in the arse end of absolutely nowhere, at a spectacularly inconvenient time of their choosing but what do you think the result will be? So despite nice wide, empty, multilane roads, no one speeds.
Likewise on motorways back here in the UK with variable speed limits, they are enforced. By and large, people stick to them, it isn't worth the ticket.
Plus also, when the reduced speed limit signs come on the road is usually clogged anyway (they're more the speed you wish you were going), so there's nowhere to speed to: any route ahead is thoroughly blocked.
Highway, implies both high capacity and high speed.
I mean kinda. High capacity, sure, but many big roads are notorious for traffic jams.
If I wanted to average 25MPH on my commute because less space, Iâ(TM)d probably drive some back road every morning, taking in the scenery and maybe some fresher air along the way. Zero point in getting on a highway that isnâ(TM)t any more efficient.
Depends. Google fucking loves diverting me onto minor back roads for a theoretical 2 minute gain. I wish it would stop they're usually more of a pain to drive than sticking to major roads. But anyway the massive rise in rat-running due to satnav has caused a lot of councils to block off rat running routes, to keep heavy through traffic away from residential areas with inadequately sized roads.
The actual fix for congested roadways is firing the incompetent middle-earth management who canâ(TM)t find a duty beyond cube farmer overlord, and make WFH actually work.
Also viable alternatives to driving. My commute is a dead predictable 25 minutes if I go by bike and a slightly less predictable 30-35 minutes by bus. I'm not going to go back to WFH. I don't like doing it and it's not a fit for my job anyway. I've got no room for a Colchester 2000 at home for starters.
