I managed to get a reading today. Found an available OPP officer and he seemed amused by my request, but obliged nonetheless.
So while my car indicated a steady 100 Km/h, his laser lidar showed 97 km/h.
The dealer says all the settings are fine according to the manufacturer. So I guess the flaw is by design!


While this sucks, I wonder if there's any tuner out there that would allow tire dimension tuning.
