Solving one problem generates another

We all know that if you want less of something, tax it.  The Colorado DOT is looking to have less traffic so they have started testing variable tolls – when congestion is bad, it costs more to use the road.  Problem solved.  But that creates a new set of problems for JIT and other time-sensitive deliveries.  Will carriers start to provide rates based on the appointment time?  So now the problem has transferred to the shippers and carriers.  I suspect carriers will just set the toll charge to the maximum and pass it onto the shipper.  Has anybody got a good solution?
