Popcorn time!
Well, after that admission, and seeing as VW sell their vehicles with the cheat technology in all states in the US, this seems to open them up to the biggest class action lawsuit ever! 350 million US citizens (plus legal residents) can sue VW for increasing the risk of them developing lung cancer due to the emissions of those vehicles. The VW management knowingly let the emissions breach the limits whilst also knowing the possible effects on health, therefore it seems a pretty open-and-shut case. I hope they all get individually sued AND given hard jail time, it might make other manufacturers think twice about cheating environmental limits again.
