But it leaves me deeply suspicious. Having some insight into what it took the team at Google to get theirs to work I find that unless GM starts with that team, and their patent portfolio, this will be be a longer term thing. I'd put money on a self driving car from someone before 2020 but 2015 seems a bit early.
In spite of Google's fudging the delicate bits (see my comment on the drive thru non-experience) they have done a tremendous amount of work that a car company would be hard pressed to duplicate quickly. That and Lidar or their functional equivalent systems are still darn expensive.
That being said, I think it is AWESOME that we've got a major car company putting this stake firmly in the ground. If nothing else it will motivate a response from the others.
