Irvine is one of those places where everything has to look just right. There are laws about how you must keep up your yard and where you can park your cars and what kind of vehicles can be in the driveway (no pickup trucks!) and what color you can paint your house and all that stuff. The example we used to hear was that although the corporate headquarters for Taco Bell were in Irvine, the company could never get the approval to have one of their restaurants in the city! In other words, I'm not surprised that their bike paths are well kept!
