Self-driving cars will "cruise" to avoid paying to park
So, do taxis cause a parking problem?  No... taxi's are on the roll because if they are parked they do not generate revenue.  Every sensible self-driving car company out there is pursuing a ride service model.  I don't see people taking a self-driving car that they own down into the city center and parking it there while they work 9 to 5.<p>Once self-driving ride services become competitive, people will own far fewer daily commuters.  They will put their money into a 4WD that can take them skiing, and leave it in the driveway on work days.
