However, you almost got yourself killed by riding like an idiot.

I don't understand all the bickering about who broke what law. So what? No court of law can bring you back from the dead by convicting someone else of manslaughter.

Your number one priority is to stay safe. If that means that you need to at least try jumping through a snowbank because you're too slow to outrun a plow, or even err on the safe side and turn off a block early, then that's what you do.
