Perhaps it's not about completely getting rid of cars but if we could reduce car use by even 25%, surely that's a target to aim for?
I'm not the biggest fan of driving and have a real aversion to traffic. I'd much prefer to be on a train than in a car, in those circumstances.
I find it incredibly frustrating that the last 8 times I've actually wanted to use the train, I've only been able to twice - due to strikes or cancellations.
