Doesn't broad legislation like this hinder new technology advancements that could benefit drivers and improve safety? How about HUD displays wearable or projected on the windshield providing information at a glance instead of turning your head and looking for the idiot lights on the console. Some of these HUD systems can improve safety by improving early warning during poor visibility as well as traffic alerts such as warning about accidents ahead and warning you to reduce speed.
Where was the legislation when complex audio systems were introduced that require more attention from driving to operate? Handheld devices are just 'another' example along with Google Glass that are additional distractions 'when used in an unsafe manner'. Better get rid of the AC/heater controls as they are just a distraction from the driving task as well. There are already laws on the books to address negligence. Do we really need to add laws specific to each new device type that comes on the market?
