Speedometers, on the other hand are unaffected by these issues.
    If you drive like hiram the tires are usually turning faster than the vehicle is moving.

    Am I right in iterpreting that as "With Hiram, the wheels are spinning, but the car is going nowhere?"

    Either could be more accurate. Both have significant sources of error. As mentioned before, you need something much more accurate to determine if it is your gps or your speedometer. But, instead of blasting by a cop, try the old fashioined way: find a measured mile, they are everywhere! Drive at 60 miles per hour using the gps. It should take 60 seconds. Then, repeat the test with the speedometer. The closest to 60 seconds wins.

    Okay, that just takes WAYYYY tooo much time! Blowing by the cop is much quicker and easier...unless of course you have to pull over, show license and registration...get a background check...show him the GPSr for proff of what you were doing...blah blah blah

    i agree, but as long as you don't stop you shouldn't have a problem... unless you drive slow...
