The dramatic reduction in parking is a common and reasonable conclusion, but I think the reduction in traffic is not so clear cut. Driverless cars will reduce the cost of trips, likely inducing more demand. You could also argue that empty driverless cars (say those travelling between fares) naturally add to traffic levels, though this isn't a strong argument.
