Fair enough, not everyone will have the same experience. The busses can suck; at least the metro is tidy and runs well. My cousin in Georgetown doesn't have a car, and he manages to travel to and access everything he needs, including going out to Potomac or Silver Spring. Going east/west is tricker, but on the flip side DC is rather small for a major city, and they're building the purple line. Public bikes and scooters are also everywhere which is nice for visitors. Additional bike lanes and connectivity is needed for sure.
Compare to Baltimore, where they have the one metro line, which is broken half the time.
