Any estimate of how much the sensors as well as compute infrastructure cost in something like the Model S? $100, $1000, $10k, more? I'd love to learn more about the increasing "computerization" of cars. Do you know of any good publications, blogs, etc for someone to learn about the computer systems powering cars?
