I have been driving past a construction area for the past week that has one of those radar stations with a display that shows your speed. They flash a warning for you to slow down if your going faster than the posted speed limit. I have noticed that no matter what speed I drive by that sigh at I am always 2 or 3 mph slow. I installed a speedometer app on my phone that uses gps and it shows the same result. Has anyone else noticed this? I know all cars are a little off but I wonder if all our Tellurides are reading slow.
