Yeah agreed, 11mph seems crazy. Usually in Europe they give a 3km/h margin, to prevent discussion around miss-calibrated camera systems and errors in the speed indicated within the car. But anything above that and you get a ticket.
Cameras in Sweden trigger at 6 km/h over the limit, apparently. Picture taken at a distance of 14 meters. Seems reasonable as well. Gauges in cars are calibrated to show slightly over actual speed, as a safety precaution. Drivers all know this, so they usually drive 5–10 km/h over the limit instead (which is their own fault, admittedly). But if you don’t have cruise control it’s easy to drift around the speed you’re trying to hold even when trying to drive right on the limit, and ~5 km/h in either direction seems like reasonable drift.
I recently bought a new car and found that, basing upon the difference showed on my speedometer and the google maps displayed speed, it’s closer to 5% over actual speed until around 100km/h when it falls to a flat 5km/h over (tested up to around 130km/h displayed speed). All cars are calibrated to show higher speeds on speedometers than actual speed, but the variance isn’t always as high as 10%.

Yeah, all cars I drove consistently showed 10% over the actual speed I was going, when compared to GPS speed.

Currently driving a 2025 Volvo EV which shows 1–2 km/h over actual speed at 40 km/h.
Yeah I was only driving analogue shit boxes from the 90s ;D
