On Youtube there is the crash test performed on the old style VW Beetle. I think that the Beetle might have done slightly better. I this day and age there is no excuse for crash performance of the dismal level. I have seen crash test of other Chinese makes and those are disturbing as well.
America is land of the tort home of the litigation attorney. If someone starts to sell those cars here what insurance company is going to cover them and at what price. Sure the car is cheap, but the premiums will likely be sky high. I can see law suits to keeps attorneys employed for decades. I don't think that the car company in China would be within reach for a suit, but the business that sells them in the US would be. Want to sell Chinese cars?
