Re "midwestern highways": haha, I don't see a "self-driving" car navigating the I-90 in Chicago anytime sooner than SF. ;) At least SFBA has super mild weather

Re "midwestern highways": haha, I don't see a "self-driving" car navigating the I-90 in Chicago anytime sooner than SF. ;) At least SFBA has super mild weather that makes the obstacle detection problem much easier. Here there are only two seasons: winter and road construction. (But yeah, we are very far from cars navigating urban areas, or indeed anyplace where weather is inclement and so are people.)
