Its too easy to get about using a car, our infrastructure is set up for the car, I was without a car for many years, I managed to get about, but when I got my car I realized that being car free was restricting where I could get to, and it was often difficult to get to some places, If I take a trip to a nearby town, in the car its about half an hour, on the bus it takes over an hour and involves two buses, no wonder that people wont move away from there cars.
Yes in rural, but fairly well inhabited Eastern County Durham, several journeys are either totally impossible by bus or stupidly difficult. I worked in Darlington, or rather on the outskirts of Darlo'. While we have a fine service, the #7, running regularly from Durham to Darlo', getting to the outskirts would mean catching the first #7 bus out of our village and then the local bus, arriving 10 minutes late for an 8am start.
Cycling I could have an extra half hour in bed, and driving, an extra hour. When I changed jobs to Stockton, centre, It was impossible to arrive by 8.30am using the bus. Cycling took a pretty reliable 1hr and 3 minutes in and rather longer, anything from 1hr 20 to 1hr 45 minutes home, depending on the wind. Driving a little over 20 minutes each way.
While I 'could' have lived closer to work, moving house each time you change jobs is more expensive than buying and running even a rather good car, for quite some time, and I already owned a car.
