It's probably safer to just mutter a correction under your breath and move on. Or, even better, give people the benefit of the doubt. Assume they're rushing to the hospital, they're child is
choking in the backseat, or they're distracted because they just worked a long night shift at your grandmother's nursing home.
No, because that solves nothing.
Oh, you're rushing to the hospital? You sure don't look like an ambulance, but please, violate all the laws you want, sir.
Uhh if your baby is choking, wait, what the f*** was the babby choking on? Seems pretty obvious to not give your child a bottle WHILE YOU'RE f***ING DRIVING
Someone is distracted or tired? Again, that's not an excuse for bad driving. In fact, if you feel that you are not capable of driving safely, yet still get behind the wheel, then you have shit for brains.
What the f***, how hard is it to just not be an asswipe while behind the wheel?
