Sorry to hear about this. I hope your injuries heal quick.
Just the other day, I had a police car allof a sudden want to cross the middle median on a separated highway, about 2 cars in front of me. The police car didn't put on his flashing siren lights or anything, just turned on his left turn signal in 70 mph traffic. It caused quite a disdurbance with me and several other drivers and as I passed I laid on my horn.
I hope you and your friends come out of this situation without any serious side effects. Keep us posted, we care!
