While what Steve says is true of many countryside areas, it shouldn't be assumed it is a country problem. I live towards the edge of a major conurbation in England. Not far away is a science park cum offices where I work once a week and can get there during office hours with around 20mins driving. My daughter had a part time job almost opposite but because of her shift pattern I could not take her on that day, and I work elsewhere the rest of the time. To get there by public transport took her almost two hours each way, including a half hour walk from the nearest train station. And it was far more expensive than any petrol cost.
