....until it's too expensive. Actually, quite a lot of people in London
have managed to give it up, haven't they?

There are other modes than rail; bus, walking and cycling to name three
- what the 94/6 split doesn't give you is
any idea of the relative length of journeys - obviously modal shifting
the shortest 6% of car journeys has less effect on CO2 emissions and
energy use than the longest 6% of car journeys. If I walked/cycled/got
the bus to Sainsbury's instead of driving to Tesco once in every two
shops, I've reduced my car use markedly, but it's probably only a total
of under 100 miles a year across about 50 trips. If I take the train to
Birmingham and back instead of driving, it's 200 miles less car use
straight off in two trips.
