Why are cars and motorcycles that can travel at 160 mph street-legal anywhere?  Such vehicles should be legal on ly on private, properly-engineered high-speed tracks.  Audi and all other car makers are hereby put on notice that it is foreseeable that such vehicles will inevitably be driven at reckless speeds on public roads so as to maim and kill drivers, passengers and pedestrians, and that they are liable for such manifestly foreseeable misuse.  Unsafe at hyper-speed.
