Just picked up this item on a computer information website:
The U.S. Department of Transportation, in conjunction with the National Highway Safety Transportation Administration, recently released voluntary guidelines designed to help automakers create safer in-car technology by limiting the amount of time drivers take their eyes off the road.
Specifically, the guidelines would limit the amount of time a person can interact with the vehicle’s audio / video system to two seconds. Furthermore, systems would be limited to just six screen touches over the course of 12 seconds while manual text entry and the display of websites, social media, books and other text would be banned while the vehicle is in motion.
Current guidelines allow drivers to read messages and perform complex tasks while the vehicle is moving slower than 5 mph. They also permit up to 10 screen touches over the course of 20 seconds while driving at normal speeds.
I assume European manufacturers will have to comply with these 'guidlines' if they intend to sell a model in the US.
