Never did the car insurance thing.
I am a good driver even when drunk (don't do that much anymore). It has saved me thousands and thousands of dollars.
My thought process is basically if i get in a car wreck which even if I was a crap driver, say is once a year. It will likely be a fender bender and the deductable will be more than the repair.
Rip me all you want but it has worked great so far
