National Transportation Safety Board Chairman Deborah Hersman also criticised the makers of in-car IT, saying they are more interested in producing things that sell than things that are safe.
Regulators in the US say 3,092 deaths in 2010 can be attributed to distracted driving.
Ms Hersmann says the 'myth of multi-tasking' has to be dispelled, asking what's the price of the desire to be mobile and connected at the same time?
Her comments came against the background of Intel setting up a $100m fund to spend on technology for the 'connected car'.
