I should probably have been clear - I do use the train. (I was one of the Extinction Rebellion protesters in London recently, so have very firm beliefs about modes of transport). My point was that the vast majority of people just won't give a shit until it hits them in their pocket. I don't see that changing, so the only real way of doing anything about it in any reasonable time frame is to make driving much more expensive and public transport much cheaper.

I disagree with your point about public transport massively improving since the congestion charge though. In what respect? I've been regularly travelling in London since the mid 90s and haven't really noticed much beyond the re-opening of what used to be the East London Line. I get the feeling that things are starting to improve now, after some serious public investment, but it still feels like too little. Until peak-time commuters aren't packed into trains like sausage meat I doubt much will shift in terms of behaviour.
