One of those trailer mounted speed monitors that they park on the side of the road and display your speed. Make a couple of passes by one at different speeds and you will know about were you are.
A GPS unit will tell you also.

In Germany there is an company that can recalibrate them (with tiresize, etc. in there mind).

An bicycle-meter works good.
