I'm being sucked into the black hole that is DC. I'm only going 80, but space time already seems attenuated. Holding true to 50 as my north star.
As for the internals of this transit, 50 westbound through DC is an inscrutable Black Box. Just know it requires 6th St NW and Constitution.
And as for driving DC, knowledge of the Rutherford Gold Foil Experiment will inform your assumptions regarding the apparent likelihood of hitting other vehicles, for I have not, so far, done so. But eventually there will be that massive nucleus in my path. I can feel it.
