While that's true, it's not as big a deal as you'd think if these cars are dramatically safer. Auto insurance is a 180 billion dollar industry in the US (that's a billion with a B). If the cars are actually safer, they will have dramatically lower insurance premiums, which will allow the manufacturer to charge more money for the car upfront and still come out ahead even if they assume lots of liability. People will find a way to make it work because there's just too much money to be made.
