Yeah, but they are still just cars. They will still need valuable real-estate for roads and parking and storage. What these are starting to sound like are trains and buses, which have existed for hundreds of years.
The difference between a self-driving car and a bus/train is that the car goes wherever you want, just like a manual car.
I'm now imagining huge traffic jams caused on purpose to enable electric vehicles to crawl around the city for several hours to avoid paying massive parking costs.
