I generally like what Elon Musk does, but this sound to me like a patch for the cities that works extraordinarily well with his other business Tesla. What we need is more and more sustainable public transportation. Trains, subways, etc that can last 40-60 years without replacement. Tesla cars "might be" eco-friendly but building cars, batteries, etc is a pretty wasteful thing if you have to replace your car in less than 10 years... Just wait few years until new cars start having forced system updates that block your car and ask for a replacement.
