Great idea ! I wonder what the cost per unit ? I see a lot of problems using it in the USA, not going to go there. Now if they can let me see traffic signals without being 2 miles back.

On average, semi trucks drive about 140 billion miles a year in the U.S. (as of 2006). Sixty-eight percent of all goods in the U.S. are delivered by semi truck. That works out to about 60,000 pounds per American every year, although the two largest commodities by weight are agricultural and building materials.
