Self-Driving Cars Would Slash Traffic, End Street Parking

When you see black and white photographs of residential city street scenes 100 years ago, there's a complete lack of parked cars. That?s not surprising given that only the rich owned them.

Because people will likely no longer own vehicles but rent them when the need arises, it will result in a massive cut in the number of vehicles on the roads.
