Quite frankly, other than GPs and a dedicated autoseeking 'Traffic' radio I think all other 'Entertainment media' are just an unnecessary distraction in a vehicle and should be designed in such a manner that they cannot be tuned, altered, programmed etc., while the vehicle is moving/engine is running. As a safety incentive anyone buying a car who specifies that none of these items is to be fitted should get three 'Get out of jail' cards for speeding offences.
