This is the first step to that solution, though - if all cars are self-driving optimally, that 2-4 hours rush becomes much shorter.

Automated cars can in principle make subtle, shockwave-damping decisions in high density flow, zip together neatly at on ramps and make space for lane crossers at off ramps. And bonus, they can also in principle be doing useful things rather than occupying parking lots.

I expect a slow phase change to car-as-public-transport that never stops rolling when it isn't in maintenance.

Way more cars are needed during rush hour than other times, so I think even in the future cars will stop rolling.

I think it is likely that the rush becomes longer

[imranq]

the biggest change would come from carpool adoption

Perhaps make huge autonomous drones that can airlift your tesla from one spot to another, bypassing congested areas.
