My car is insured through State Farm. I have no collision insurance. However, I noticed my comprehensive coverage (theft, vandalism, weather, etc) only had a $250 deductible. I increased that to $1000. I also noticed that I only drove 7,200 miles last year. State Farm has a low mileage discount, and I just had to email pictures of two service receipts (about a year apart) with odometer readings as evidence.
My new-found bicycling habit is partly what made this possible!
