I don't think there's a clear answer to that question, but my gut says that would be immoral. What we'd be doing is saving a ton of lives where people would have otherwise gotten themselves killed through their own choices, but at the expense of a few deaths where the fault is entirely our own (the car maker). It's laudable to protect people from themselves when it doesn't otherwise affect them, but when the cost is killing totally innocent responsible people, I think it crosses a line.

On the other hand, if you think fault doesn't matter and it's just one life for another, then it essentially becomes the trolley problem, which doesn't have a clear answer either.
