All of these things will help influence people to use alternative modes of transportation. But when it comes down to it, everyone must make a personal choice. Bicycles will probably never be as convenient as automobiles, and in this writer's opinion, they shouldn't be. Commuting on a bike is a sacrifice in some ways, but we need to set our priorities straight. No legislation will do that for us.
Boulder is probably one of the best place to get into the habit of frequently using a bicycle.
In this community bikes are generally a lot more convenient than cars, in pretty much every aspect. Probably more than half of the time, I can get to wherever I want to in less time on a bike than in a car. Not to mention the time saved by not having to find a parking spot. This is accomplished by the use of good bike routes, underpasses, and having the right of way over cars. I use my bike almost daily, whereas I would probably use a car about once a week.
