It would still be the people going too fast who cause the accident, even if there’s many of them.

Yes, morally. Physically, they have to hit something for there to be an accident. If you’re not there, you can help prevent an accident. That doesn’t mean it’s your fault if you’re following the laws and that is a non-proximal cause of an accident, it just means that defensive driving best practices and the laws are in contradiction.

BMW drivers are the worst. Along with Audi and Mercedes drivers.
