Implications of self-driving cars

One important implication is more consume. If people get from A to B per car without paying attention on the road, they can consume more entertainment, do more google searches, spend more time on the web.

Capacity utilization and efficiency is just a fall-out. We already sleep way too much, you cannot do anything about that, but the 'Googles' cannot tolerate users (customers) driving around 1-2 hours a day doing nothing but starring on the street.

OK, so now you've laid out what happens if everything goes perfectly. Now list what could go wrong and your best estimates of their likelihood, and tell us what a mixed success would look like.
