For one thing, it was designed to be graffito-proof. The dim lighting

The dim lighting results from having dim lighting. Even the stations
that have painted the originally unfinished concrete with white paint
are DARK.


There's no circular line. While it's theoretically possible to ride
back and forth all day, then get out at a station nearby, it's still
not a convenient sleep. And the Metro card may be time-stamped to
prohibit it--I don't know.

The system doesn't run all night either. Originally it closed
at midnight, but that's been extended of late.
