I'd want to put some unbelieveable mileage on the car so that it looked like the car did something like 6,000 miles in a 24hr period which would be 250 mph. Can you imagine the reaction when their immaculate computer spits out a 250mph average speed?

I am not certain that the GPS records where you have been (that would require a lot of non volatile memory). More likely that it keeps peak velocity (only one parameter to remember, not a series of parameters).

I like the idea of trying to make the rental company think that their car did 400 laps at Indy at a speed that the car cannot possibly achieve. ;^)

"Sir, according to our records, you achieved 95% of lightspeed and went to Jupiter and back. This, of course, forfeits your deposit."
