How about european legislation to reduce pollution and fuel waste, as well as personal frustration in peak time queues for tolls? A clear example must be the M25 crossing, the cost of fuel wasted far exceeding the cost of the toll. How about sensors placed in the road to repsresent a 20 minute wait, so once traffic exceeds this point the toll gates are opened for free passage? It would also greatly help on the French holiday routes on peak weekends, where there is no apparent urgency to process vehicles once it's your turn to smile and hand over the cash! At one point we waited nealy an hour to throw _1 in a basket!
