The cruiser was going at least 130mph, without lights or siren on, struck the car at the b pillar and literally sheared the car in half right behind the driver. It was unreal, the two pieces of the car looked like they had been cut in two by a giant table saw. The front end of the cruiser was smashed in pretty well.
Incredibly, when I pulled my car off the road to help, I found both drivers up, relatively unhurt, ambulatory and in a daze from shock. A few minutes later another cruiser pulled up, called a tow and drove the civilian driver home. It became a local news story as the police officer was not only not arrested, but not disciplined in any way. Insurance covered the cars and the officer was back on the beat in a new car within the week. His rush? He wanted to make it home in time to watch a college ball game after his shift was over.
[EDIT] this and other dangerous-driving observations lead me to treat cop cars on the road like someone I've seen through the window drinking a 40 while talking on the phone. They're far and away the most likely category of vehicle to do something batshit crazy with no warning.
I'm immediately lit up. "Failure to yield". In addition I get an FST after "failing" the vertical nystagmus test (bear in mind at this point, my one and only pint of beer is coming up on five hours old). Cop is insistent I'm drunk, says he can go the DUI route, because my "behavior" in "failing to yield" shows I'm impaired, regardless of actual numbers. I'm lucid, but frustrated. Debates merits of blood draw, etc. Tickets me, "Get out of downtown and get home, I think we both know you're getting off lucky".
