I think the trouble with many media organisations (including the BBC) is they just quote soundbites from one lobby group in one article, whereas they should always get both sides of the story.
Lobby groups are incredibly clever at distorting arguments through statistics, and you need some knowledge to cut through the crap to make a considered opinion.
It's very easy to get to stuck up on things like 'It will cost every family £1000' and most will gain no benefit, when the truth is transport schemes HAVE to show benefits derived from a universal framework to get ANY approval. The very same people who make the same arguments are also likely to believe people should pay for their own education, and why should I pay for X persons child? Again the reason, like decent infrastructure, a well educated population allows us to compete with the rest of the world and have a decent standard of life.
Take the quote from the RAC trust, that more should be spent on roads because 93% of passenger KM are by this mode. What isn't pointed out is there are over 24 times more roads than railways (245,000 miles v 10,072 miles). Given that rail passenger KM have grown faster, and there is a hell of a lot less of it, and on some of the main line sections the railways carry far more than the competing roads, you would think the logical solution was to improve the railways, especially as they fit more in with some of the other [Government] objectives concerning energy prices (and demand), congestion, pollution etc. The same organisation also points out that rail spending is comparatively high right now compared to roads. Yes, that's because 1) past underinvestment 2) the trunk road network is effectively complete 3) projects like Crossrail or Thameslink, in dense urban cities (areas where rail is usually the better solution than road) are always going to be more expensive than say bypasses in Lincolnshire (where road is often a better solution than rail).
