Around here they don't even move over, or slow down for flashing lights on a cop car or a tow truck. A car on the side of the road with 4 way flashers on means they honk at you as they fly by 15 mph over the speed limit.

We have had several State troopers killed when some morons plowed into the squad cars with flashing lights turned on. The squad cars were off the road surface, and almost off the shoulder, but the fools still crashed into them.
We have a 4 lane bypass for our town. A state trooper was off the shoulder of the road fully lit up, parked behind a semi that broke down. Both were at least 4' off the highway surface with two lanes going in the same direction. They were standing farther off the road the the squad car towards he ditch along the side of the semi.. Some fool driving a semi, crashed into the squad car, then smashed into the semi and split open the semi's fuel tank. The insuring instant fire killed the trooper, and badly burned the truck driver. The guy that crashed into them was uninjured. No other cars around, 2 full 10" wide lanes, + 4 additional feet of shoulder and the guy still hit stuff. The estimated speed of impact was 70 mph, in a 65 speed zone. How does a guy manage to get 4' off the road at the only place there happens to be a lit up squad car and a disabled semi along the side of the road in a 4 mile stretch?

If you want to change a tire on the side of the road around here, more power to you.
