Lots of bicycle riders in England, because everything's so close and they can typically bike to work if the weather isn't bad. And they also don't have to worry about parking.... parking usually means a car park somewhere, which also means you have to pay to park, and since there's so few car parks - it's a major hassle just to find one within a 15-minute walk of wherever you're needing to go.
I drove my wife to work every morning, which was literally a 5-minute drive away. On average I'd probably see 30-40 cyclists there and back. Over there - they have a designated bike lane. But that doesn't mean every cyclist is following the rules of the road. You always had to be alert. I saw a cyclist almost get run over because he rode through a red light, and had he been hit and injured - it's like the driver of the car is always at fault - even if he's not. The local governments encourage cycling to cut down on traffic and emissions... and as a result they seem to side with the cyclists more often than the driver as far as liability goes.
I would never feel comfortable riding a bike here where I live, despite the roads being nearly twice as wide. I tend to not trust other drivers, and if I get involved in an accident - I'd rather be buckled into the seat of a car than being run over without any advance warning and protection whatsoever.
