Are you factoring in network effects? I have lived in Phoenix and Tucson, where the light rail is a joke: they are so short and there's only one line, so you probably don't live close enough for them to be useful and they probably don't take you where you want to go. If there was more light rail, more people would use it, but since so few people use it, there is little incentive to grow the light rail. Contrast Hudson County, NJ, which has a light rail system that's used heavily, the trains are often full during rush hour. You can use it to get pretty much everywhere (except Union City and uptown Jersey City, which both require a long trudge up the Palisades).
