Here you don't have to report accidents where nobody is hurt and total damage is < $2000 (up from $1000 recently). I blew the driver's side mirror off a rental on a pylon a few years back, and when I called the cops they were annoyed I'd wasted their time. They also said I may as well continue on my vacation sans side-view mirror (which was hairy as hell coming back on the 401 --
the world's busiest highway). In the end the rental company didn't bother to submit an insurance claim, they ate the ~$300 replacement cost.
