processors will get more efficient with each generation, aren't they charging their electric cars from solar panels anyhow? ;)
Oh no that's right, they mostly run on coal.

Right now with human drivers fatal accidents are increasing despite cars being much safer because people are on their phones, I watched people driving by and it's like 40-60% of people actively using their devices while driving on a busy city street, at this point I am happy when I see someone talking on their phone because then they are not texting. These things can't come fast enough. As long as they get in accidents less frequently than humans they are beneficial. And if the thing does not have a steering wheel then whoever made it is responsible if it causes an accident so that will give the makers an incredible incentive to make them have as few accidents as possible.
