I'm infrequently a driver, so I don't have status to make any of these changes, but Waze is constantly telling drivers to make illegal or near impossible left turns off Florida Ave, so I'm hoping someone can address.
Heading east on Florida Ave NW, there is signage prohibiting left hand turns onto N Capitol St NE. The signage is actually inconsistent (some indicates it's always prohibited, some indicates it's only prohibited during certain hours) but because it's inconsistent, drivers will not turn left, so that should be reflected in the map.
Immediately past that intersection, Florida Ave NW turns into Florida Ave NE, and there is parking lot that Waze directs people to turn left onto to cut through to Q St NE. This is nearly impossible to do without blocking traffic for a long time and waiting for oncoming traffic to stop and let you through. If there is an option to eliminate that route as a "throughway" and treat it only as a destination (which is accurate - it's a parking lot that happens to connect Florida Ave NE and Q St NE), that would be ideal.
