Is that actually so? In my understanding, cars that drive more break faster, mileage being the dominant factor, not age. So whether you have 10 cars serving 10 people, breaking after 30 years, or one car serving 10 people where you have to buy a new one every 3 years - seems about the same. In the former model, car makers even have the opportunity to get people to buy new cars before they'd technically have to, which sounds like more money to me. For society at large, the latter model seems better.
