Perhaps they can be trained to use them? :-)

Autonomous vehicles will reduce the need to park. Eventually.

I don't think this is actually necessarily true. Most of the AV fantasies involve cars driving about aimlessly when not in use or increasing congestion in the reverse peak towards parking lots in the suburbs during dead times, and to the extent that those scenarios increase vehicle miles traveled that might actually be worse than parking lots everywhere.

Cars are about as healthy as Daleks are for cities.
