Is that not the whole idea, and not a bad one at that? The country is skint, this makes money for the coffers instead of cuts or taxes, and will also provide work for a good few people.
The more I think about it, the more convinced I am it's a good idea. The only downside is that the country is already too small and full of roads, and that they'll only leave the speed limit at 70mph on these lovely clear roads anyway.
but i wont be spent effectively, no new roads or making things safer. it'll be a hike in petrol again and have to pay for the tolls too, with no benefit for the motorist.
it'll just be the companies that run the roads that get rich!!
