Took our new M3W out on the highway for the first time yesterday. At an indicated 70 mph I was being passed by everything on the road. So I asked Molly to bring up a GPS on her phone. I was only going 64! Now I know why that cop didn't chase me down when I thought I was going 80.
Squirlz - same with my 4/4 Sport but looking at the BIG plus side, when you enter that 30 or 40 zone and the camera van parked a mile up the road targets you, you can still smile at an indicated 32/43 as you wont be contributing to funds.
It's a bit annoying but you'll learn to live with it!
Cheers
