I said light rail (trams, streetcars) is non-existent. There is a test line in South DC, but nothing that’s actually useful for commuting or getting across the city.

My wife tried to use Metro for her Reston->downtown commute. It was a disaster - rail delays made it completely untenable. Then she tried the bus. It was more consistent, but overcrowded. She ended up driving 4/5 days because it was faster, cheaper, and more consistent.
