What I don't like about DC is the "speed" of the metro: slow slow slow - and for some reason there is constant acceleration/deceleration/acceleration/deceleration etc. etc. etc. Not a smooth ride at all, unlike BART. I often (jokingly) think that DC drivers should take classes from BART drivers, since it seems that the systems are technologically similar....
