I'd agree with pretty much all of that. People don't, mostly, drive because they're petrol heads but because driving is perceived as, and very often actually is, the most convenient way of getting somewhere. In this respect they are the diametric opposite of cyclists, who cycle for the cycling itself, not to reach a destination. So, a lot of people drive despite seeing the damage it does in terms of pollution, noise, disengagement, etc etc (which isn't to say that a lot/most are oblivious) but apart from a few whacky coal rollers and the like, no one actually wants those things - they're just a price that has to be paid. So making driving inconvenient or prohibitively expensive is the thing that will get people out of cars. It's all a matter of scale, really. When half the households of the country had one car and the others had none, it wasn't a big problem. Now that half have one and the others have two or three, it is a big problem.*
*Just like a lot of things, but that's going OT.
