I don't drive, but if the government really wants to make people leave their cars at home, putting up car tax and petrol duty isn't the way to do it. What they have to do is make public transport much, much better. I'm lucky with work as my office is only a few minutes walk from about four different bus routes. But I went to see my parents last week and I had to catch two buses, which took nearly an hour, and if I missed one, it was an hour wait for another. In a car it would take 15 minutes.
