This is a good idea, since most new cars have tons of electronics, instead of the good old mechanical odometer.

My advice would be to attach to a rear wheel. The front wheels usually go a longer distance because of turning and slipping.

Calibrating a bike speedo is easy with a GPS:
First, set your wheel circumference (usually in millimeters) to what you estimate is right. Drive around with a GPS and then compare the distance with the speedo. If the speedometer is x% lower than the GPS, then input a circumference x% larger. The farther you go, the more accurate the calibration.
