Ambitious speedo

Drove by a police YOUR CURRENT SPEED thing and my speedometer read ~35 but the police thing said 30. Not a huge deal but anyone else notice this with speedometers being off?

Mine is the exact opposite.

Running 33's and stock 3.55 gears when my speedo says 30 I'm actually doing about 35; when my speedo says 60 I'm actually doing about 70.

I have a properly calibrated speedo, but I will confirm that the speedo tends to err on the high side at low speeds. My speedo is very accurate above roughly 40, but the slower I go, the less accurate it is. It's probably just a limitation of the specific system used.
