Parking is one of those things that could be improved for biking. I really hate most of the bike racks that most places use, and if you get a bad one it can take a significant amount of time to lock up your bike. And, a big reason why locking up a bike takes a while is that bike theft isn't really treated seriously. IMO if bike theft were taken more seriously you wouldn't need to make sure you had an excellent lock and had your front wheel secured, etc. Thieves would be much less willing to take the risk of stealing one, so a simple chain would be enough to discourage most thieves.
