And if your speedo is 2 MPH off at 10MPH and still only 2MPH off at 100MPH feel lucky, the speedo was blessed by god himself.

its 2 mph off at 20 30 40 50 but he is still a cop and wouldnt let me speed so i couldnt test any faster and what did you mean by "more the speedo needle" im sure its just a typo but i cant think of what you might be trying to say
