I drive 5 miles under the limit, in the left lane, with my blinker on.
;)
Protip: Every speedometer I’ve ever compared to Google Maps or the free android GPS Test app, consistently reads 55MPH when your actual speed is 50MPH, regardless of whether the scale is metric-only (my bike) or dual-scale (every production car in America for nearly half a century, now hidden because it’s driver-selectable).
Comclusion: If you think you’re driving 5MPH below the posted 55MPH limit, I am confident that your actual speed is between 44 and 45MPH.
Your mileage may vary.
Moi aussi ;-)
