Ineffective ERP

When one pays ERP charges, one expect to travel in a freer road. When one pays 50c, the quality of the road flow may be lower. When one pays $1, it should be better. When one pays $1.50, it should be even better. But if after paying for all the increases, the condition is still the same, then should not the authority return to the 50c rate since there is no improvement and the flow is as was at 50c level? Ok, the authority can say, we will increase the cost to $5. That should do the trick. I think that should be the answer. But wait a minute. When transportation is going to cost a bomb, then business cost is going to shoot up as well. People's cost of living will also go up as well.
