Plus, in a ton of states, driving is a privilege, not a right. I've lost my license a few times after the judge in question said I was justified but some bureaucrat in "public safety" or whatever didn't care about the life-threatening issues at hand and just yanked that privilege. Bureaucracy is hard to undo, and even if it weren't strictly a matter of improving my chance to live I'd much much much rather take a pill and a slow, safe route to the hospital than spend one more God-forsaken winter biking to work in -20F.
