The ADAC part with which all newly type-tested cars have to have a tyre pressure control system from 1 November 2012. Must be so much technology? In the near future you have to make a special vehicle certificate to lead a vehicle at all. So probably soon the vehicles that no longer come through the TÜV are not scrapped because they are rusted but the repair of an unusual techn. is partly more expensive than the vehicle itself. I myself have nothing against technology but they must be be useful and above all affordable! How do you see this?
