Update:
The traffic signal at Eye and NJ SE, where this incident happened is in place. The PBL’s on NJ now run all the way south to US DOT HQ. NJ and Eye is now a protected intersection, one of the first in the District (its a bit odd, because of the angle caused by the state avenue, and the inconsistent presence/absense of parking on the different lets of the intersection – you’d have to ask Darren/Bikepedantic about that)
Things DO get better. Slowly. Painfully. Inconsistently. But they do.
