I could see Google saying "Hey our car works. License our patents."
No, Google will offer it for free and then display ads for every store and restaurant on the way asking if you would like to stop.
Some people call them revenue raisers.
That is what they are. Speeding isn't that big of a cause of accidents, but it is the easiest to ticket because it is measurable. When everyone is doing 20mph over the limit on the highway, there is no issue. If one person is doing 20mph faster than everyone else and weaving between lanes, that is an issue. Worse if someone is drunk, talking/texting on a cell phone or distracted with something else. I'd rather work on detecting these drivers as they are the real danger.
