I was coming into Worcester on 290 and saw brake lights, so I slowed down. I blinked and next thing I know there was a sedan right in front of me, stopped dead, and all 4 tires were sliding. I hit him at like 15-20mph and screwed up the header panel / other assorted stuff and put a small hole in the radiator. The guy I hit said he wasn't even sure if he hit the guy in front of me first or if I hit him first it happened so fast, it was a real shitty time to come around that corner. Wish I'd just left work late, would have avoided the whole mess.
I limped it home, it runs and drives and whatnot but is totally not legal, lights are smashed, bumper is stuck to the crossmember, etc. As long as I can tell my insurance company that I'll fix it and to not bother sending an assessor, I am not worried about it that much, but it's going to rape my insurance premiums

Would have been better for me if the guy behind me had hit me as well, but he narrowly avoided it so I ended up as the back guy.
