Unless cars become extremely cheap (they have done the opposite), it will never be acceptable for them to be disposable. Materials and processes are better than ever yet cars are becoming less repairable. Manufacturers deliberately make things difficult to repair to encourage people to buy new cars, but that only goes as far as people will tolerate it. We aren't talking about pocket change. A new car is usually in the top two largest purchases anyone makes, and they really should be built to last at least 20 years. There's no reason why they can't be built to last 50 or 100 years, or indefinitely (with repairs).
