Please explain to your son he has nothing to worry about if he is abiding by the Motability rules they are not watching him 24/7 its only there in case there is an issue most cars nowadays have a SIM card which reports back to the manufacturers and probably Motability they will only start to look at the data if there is a problem or an issue with the way the car is being used Ie for Amazon deliveries or uber/ just eat so anyone who has a modem Motability car will be tracked and the data recorded so don’t worry
