Model S is the best car I've ever owned, and makes such vast improvements in pretty much every area over normal cars. The technology, performance and environmental friendliness are years ahead of its time; however, two places it is the same as other cars are the tires (wear and tear, road noise...etc) and the seat belt (having to manually buckle). 1. I'm wondering if Tesla put in the same effort in re-engineering tires -- designing from the ground up -- as they do for the rest of the car, could they make a next-gen tire that solves these problems? Are they even trying to do this, exploring different designs, materials etc.? Or are tires as good as they'll ever be? 2. I'd love to see an automatic seat belt that works perfectly. If it's possible to make a robotic arm for charging, seems possible that a robotic arm or some other method could buckle the seat belt. Full disclosure: I've chewed through thousands of dollars worth of 21" tires so I'm a bit biased in wanting this What other parts of the car have not been improved over ICE?
