Looks like it has no trunk, which is a huge use case for self-driving cars. How many trips do you make just to move things around? How much of what you own would you rather rent if you could have it delivered within 15 minutes? Then there's the economics of prepared meal delivery... I'll be surprised if passengerless cars don't outnumber passenger cars in 20 years. As for moving people, a significant part of city bus fares goes to driver salaries. And other vehicles tend to avoid buses / don't rely on making eye contact with bus drivers. And buses follow predefined routes. So it's surprising to me that Google is going for private cars instead of city buses as a first market.
