I appreciate that driving is harmful to the environment, as well as being a relatively unsafe form of transport. And don't get me wrong, I'm a great believer in public transport generally, and do use it *most* of the time. But as a general rule of thumb, if a journey is going to take me double the time on public transport, then I consider getting in the car instead. Call me selfish if you like, but I believe that I am in the majority here. I just think that the emphasis should be on improving public transport, rather than taxation on motorists. That way, driving becomes the priviledge of the wealthy, which is surely not right.
