I did a GPS v Accord speed check today and found the Accord to be surprisingly close to the true GPS speed. Found a difference of ~1.6 mph at 30, <2mph at 40 and ~2 mph at 60 with the Accord overreading in each instance.
Much better than I expected and reasuring really, now I don't have to convince everyone in the car that I'm only doing 30 when the speedo reads 34 (not that anyone else can see the Accord speedo easily)!
