Re: Hybrid vehicles...
Unless you privatise all road construction (not really possible and only arguably economically sensible) you cannot really market price road access. If you did, you might well find high prices for city centres, since the land value is high to establish high capital costs, and the demand for usage is high.
The current UK government has plans to move to road pricing, but that wouldn't be based on market prices. What price Oxford Street per yard, or Deals Gap on a Sunday?
Change is as good as a rest!
