When I ride my bicycle and do 25 to 30 miles per hour it is faster the a car doing the same mileage based on the readings of the odometer. Why is this?
Virtually all car speedometers are deliberately overclocked, usually by between 5% and 10% (to judge by comparisons with roadside speed warning indicators), to make you think you are going slightly faster than you are!

Actually, it's more of a hypothesis based on years of observation (I think someone from the automotive industry did tell me that once as well - a long time ago!)
I guess your comment, that I should definitely know this, is based on my having spent my working life in Rolls-Royce. However, R-R hasn't made cars since 1971, which is before I worked there! I think the only part of a Rolls-Royce car actually owned by R-R these days is the doubleR logo, which is licensed out by R-R.
