Roads are currently designed for human drivers. Roads designed for automated vehicles could use different signalling systems for intersections and road works, and even parking (it would help if unattended vehicles could be moved at will for tighter packing).
That would be great but in reality we're going to need self driving cars which are near enough perfect with the existing infrastructure to get some major traction before roads start getting designed for them.

For the amount of money it would take to completely overhaul the country's entire transportation infrastructure to accommodate self-driving cars in this way, you could have built a phenomenal train and bus system with bike/scooter lanes everywhere.
