We need more roads: you're joking, aren't you?

In this article Study calls for 372 miles of new road lanes a year | Special reports | Guardian Unlimited, we are told the RAC Foundation have called for road building on quite a big scale. My response is pretty similar to those recorded at the end of the article. "However, the Campaign for Better Transport (CBT) said investing in public transport, not roads, was the priority. It released a poll showing that 62% of people wanted more money spent on public transport, and only 30% voted for roadbuilding. 'The RAC Foundation seems to be living on a different planet from the rest of us,' said Rebecca Lush Blum, of CBT."
