Yeah, it's a huge difference between the UK and US, I think, I hear americans talking online of happily driving an hour to go get a pizza or some sodas, whereas in the UK an hour's drive is generally a planned event. I think it's partly down to the difference in gas prices however.
I do think tho, if they dropped the prices of public transport, at least off peak, move people would use it, and they'd maybe even make more money. After all, those buses and trains have to make the trip, whether they're empty or full.
For me, it's a real boon as I can't afford to run a car for only one person, and rarely need to travel more than maybe 5 miles. The only slightly irritating part is going shopping and trying to get on a crowded bus with a multitude of bags. However, some stores offer free delivery now, so when I can I go home on the bus and wait for my shopping to catch up in a few hours
