I honestly don't trust any of that stuff yet. I don't even like the distance keeping on cruise control. Hell, the collision detection in a couple vehicles has almost caused 2 accidents for me.
They sure look great for the price. I haven't driven one so I don't know about that experience, and I sure wouldn't want to own one without a warranty :(
Does BYD have a history of lying on anything -- how trustworthy are they when they say something like this is what I wonder.
They have a big incentive to lie, or at least exxagerate.
