Unfortunately you seem to over estimate the skill of the "average driver". From what I have seen on the roads (certainly in the UK), the "average driver" has no awareness of what is occurring on the road around them. They seem more interested in twatting about with their smart phone, having animated conversation with passengers or just plain have their brains in neutral. Giving them another thing to mess around with instead of concentrating on driving is just asking for trouble.
