It's also plain old common sense. But I've seen more than enough dash cam footage of drivers hitting either police cars or the car they've stopped behind to know that it is apparently too much to expect people to act responsibly without a law enforcing it.
It's ridiculous how often I see people that won't move over for police, highway patrol, or even get out of the road for an ambulance with lights and sirens on! This is day 1 drivers education type stuff! So many stupid people out there these days! 🤦🏻♂️
