Simple is good. If you make tires more complicated there will be drawbacks. Expensive and more things to break and go wrong. There are already run-flat tires and tires with pressure sensors. The cars are the way they are because it works and it's a proven model. The basic engine designs live for decades because they work and it's not cheap to design a new one. I don't think cars suck. Some brands/models do, but in general I think they work well. A modern car is very reliable. Much better than the ones from the beginning of the 1980s. You can buy a 12V adapter to charge your car battery from a home outlet. I didn't write I thought tire chains were the best thing for driving in cold weather. I think winter tires are. Yes, you have to change the tires, but it's the best solution there is right now. Those spike spiders seem to add an additional permanent steel hub to your wheels. This adds unsprung weight to the car which is bad. The bottom line is that designs are compromises. A feature is not always worth the drawbacks.
