Monbiot on cars (and motorways)

Have you ever wonder why the Right adore motorways? It's almost onscene, their determination to build more and more of them, bigger and bolder motorways that scream to be populated by cars (one person per car please, no need to crowd!).
George Monbiot has plenty of pithy things to say about this here.
I liked this fragment:

"It seems that the door to new roads has swung open again. The Conservatives have long had an interest in getting people off public transport and into cars. Public transport is often unionised. It pools resources and encourages social mixing and collective action. Car driving, by contrast, isolates us from other people and encourages us to see society – pedestrians, bicycles, other cars, speed limits, traffic calming – as an obstacle. The car drives us to the right. It is a powerful but overlooked agent of political change"
