Ok, I'm kind of joking here.
It seems like more than +5% on my car, does this vary at all. I haven't hooked my GPS up to the car to check for sure, but I have compared my speed on those signs that flash and it seemed like more than 5%. Does anyone have any more real life experience with this?
Like at 55mph the GPS speed is blank... etc.

I use a gps every now and then (a garmin) in my 135 and on the highway my car may say 85 but the gps says 79/80ish around there so i'm guessing they are all off a little bit but not a huge amount.
