Maybe the manufacturers should pay for all the tickets (and points) the drivers get for not using their turn signals, and take full blame if a bad signal leads to an accident. Perhaps that would start sending a signal that they need to stop making things that do not work, just so they can get more money to fix them. Along with paying reparations for the damage they do to the environment with parts in landfills, and whatever other damage they do to the environment in wasted gas to replace them or because they waste energy themselves.
