Exactly. And I think it helps workers get to jobs that they couldn't get to otherwise because of being underpaid. Light rail in Houston increased the time spent in traffic since it was intended to bring people who can't afford cars or taxis into the central business district, it was built at ground level consuming right-of-way, and ended up noticably obstructing the flow of traffic that was there before. The rail was not built as any kind of a substitute for very many established automotive commuters at the time, and it still does not take many cars off the road. When waiting at a traffic signal for the train to pass, you notice how many fewer people make it across the intersection on the train compared to how many do it in their cars before you get the green light yourself.
