Not sure if this will be practical however always think the rules on mobile phones are arbitrary as are allowed to speak on a phone when driving also allowed to operate a touch screen mobile phone style interface. You can operate a phone from an ipad as long as its integrated to the dash (tesla, Cadillac)yet if you attach a phone to the dash in the same place it’s not legal , you could pair you’re a phone a device wired in the vehicle with exactly the same interface and place it in the same position.
I was looking at car videos on line and new top end cars like the tesla and Cadillac have I pads integrated in to the dash, so controls for things like heater or radio now involve taking eyes of the dash. In an a normal car you can feel every control for heater and the switches so can operate the vehicle without taking eyes of the road.
With touch screens you cannot feel the buttons and like an I phone the buttons move. I would think for safety any touch screen device should be banned from being used, so in a tesla and similar cars the touch screen disabled while vehicle in operation.
GM, ford and tesla puts style over safety with these I pads in dash, it seems strange that a controls on an old wreck can be operated more safely than the best cars.
In respect to mobile phones and cars is it operating a touch screen when driving that is deemed unsafe in which case, why are these devices not banned in cars like tesla or is it speaking on the phone that is deemed unsafe in which case why are hand free devices permitted. You are allowed to operating an I pod when driving which has the same interface as an I phone. It would be legal to drive on a hands free phone and operate an I pod.
I would tend to think non touchy feely button controls such as I pad type interfaces should be banned from being operated while driving, however this would be impractical so possibly regulation on new cars should allow all main controls to be operated with tactile location fixed buttons to allow operation while driving and the I pads controls disabled while driving.
I don’t think the government will deliver this legislation on blocking any times soon or indeed ever, the government has not even managed to align incentives on diesel vehicles the government despite the evidence, the passive smoking of diesel fumes in town centres, “encouraged” by government policy is a akin to the tobacco conspiracy of the past with greater concerns for commercial interests than health with lower "road tax" company miles tax on diesel cars.
