I rode this morning to run a few errands. After a few comments lately about speedometer/odometer accuracy I decided to experiment. I rode a specific route around town and back to the house. It was 9.1 miles. I took the car, a 2013 Ford Fusion, and drove the same route. It was 9.0 miles in the car. It's not as accurate as if I'd ridden a 90 mile loop but it's something anyway. My speed may be off some but I'm going to figure my miles ridden are pretty accurate.
