As a counterpoint, I can't imagine a better form of transportation for the area in which I live. It's hilly enough that I really don't want to try and haul my kids (5 and 11, both quite tall) around on a non-motorized bike, but our cargo bike gets us most of the places we want to go faster than a car or bus would. And I get exercise in the process. It's the most delightful form of transportation I've experienced.
