I always assume it's about gathering data. I am probably completely wrong, but frankly i feel like every large decision i've seen from Google comes down to 2 core concepts: 1. Enable more people to use your service 2. Create devices that can gather more data The thing is, a ton of device types can fit into one of these schemes. Phones for example, both let people use your service, as well as gather a ton of data. As we increase the technology in phones, they may even be mapping the environment. Likewise, these self-driving cars are able to exploit much of Google's current offerings, as well as contribute mapping of a near limitless amount of roads/etc. If Google can pull far ahead in the technology they can become the self-driving service. Even if they don't create the cars but instead lease the technology to normal makers, Google now has constantly updating maps, traffic patterns, routes, building changes, etcetc. Sure, Google made a car, but i don't think they car in the slightest about the car itself. They need to push to improve the technology and legislation as fast as they are able - everything else, people and car manufactures, will catchup eventually.
