I have used calibrated GPS in any number of cars and an indicated 20mph registers at 17 - 23 'real' mph. Ford seem to have the most accurate speedometers. Nissan seem from observation to significantly overread.  Just stick to the limit. My new car reads the limits and does not let me go even 1mph over. The calibrated GPS shows my actual speed when 20mph is indicated, as 19mph. Happy with that
