I am 31 and I am learning to drive. I didn't want to learn when I was 17 as I was an ardent environmentalist. I am less so now and have realised that it would be very useful to have a car for dd and I.
However, I hope that I don't become the kind of person who drives to the local shops or down the road.
I think if people want to cut carbon emmissions they should only use the car for longer journeys and take the bus more.
It won't happen though. Peopel like their vehicles too much.
