Maybe we could hook a bunch of cars together, especially if they're going the same direction anyway, even put some kind of tugging device at the front of the line of cars so they could save gas on the way to wherever they're going, but I'm pretty sure this doesn't exist yet...
2020 proved it out for many US jobs these days. Nobody doing a desk job goes into the office anymore. Remaining road traffic is people that have physical jobs. Desk people are plugging up the road, because their employers would rather see a body in an expensive office chair than the effective reality they already had proved out by force.
But yeah, also public transport would sure be nice.
