Why did you go off and mention road emergencies?
In my opinion, people have gotten really callous about yielding the road for emergency vehicles. Almost two years ago, I tried driving my brother, who experiences seizures, to the hospital. I had my headlights on and flashers going. The trip was about 20 miles. No one... and I do mean no one... yielded the right-of-way. I drove on the shoulder, whipped back-and-forth between lanes. Heck, a car or two even slowed down in front of me when there wasn't a vehicle in front of them. I never cursed so much in my life that day. I do not know why it surprised me. I have seen drivers stay in the road in front of ambulances with their lights on. I hope it's just a generational thing and not something permanent.
