While I enjoy an occasional megameter by car to look at the countryside
the saner (and more risk-averse) folks take a train or fly. The size of
the car is not the issue, it's how much space each occupant has.

I'd much prefer telepresence platform rental for everything but
vacations. In fact, a lot of vacations are about sightseeing, and a
drone can go places faster than ground-dwelling monkeys.

Many people in cities don't have a car themselves but use car-sharing

I would not make cars slower than 130 km/h cruise, and up to 200 km/h
for brief sprints.

Given that a pedelec in-hub does 300 W easily, and kW in ultralites
goes a long way a recumbent-type ultralite with aerodynamic shell would
be a speed demon and weigh some 30-50 kg.

Steel doesn't really have a bright future in light vehicles.

Nothing will be happening in infrastructure. If anything, decaying infrastructure
will make autopiloted personal VTOL electroflight worthwhile.
