I'll echo that for DC. If you don't know how to get from the watergate to union station via the most efficient route, or you have no business driving a cab.
This is the second time I've seen you complain about this trip. I lived near the Watergate hotel for several years and can tell you there is no automatic guaranteed efficient route to union station. The entirety of downtown dc and all of the monuments lie directly between those two endpoints. DC traffic can snarl up pretty quickly between the tourists and random motorcades and regular old downtown traffic. I'd cut them some slack.
I take the trip every day so I have a lot of data points. There is an efficient route to Union station from the Watergate that's almost never backed up: take Rock Creek Parkway, to Independence Ave, to I-395, exit 10 to D Street. You can be forgiven for taking Constitution, but if you take K or H, you're guaranteed to be stuck in traffic.
People who don't take this route, I imagine, either don't know Rock Creek Parkway opens to southbound traffic at 6:30 pm (I travel at 6:35), or don't know that while 395 is a mess on the VA side, it's usually clear sailing for the short stretch from Independence to D street. This isn't obscure. Rock Creek Parkway and 395 are the only freeways running across D.C. Anyone who is a professional driver should be intimately familiar with the traffic patterns on these two roads. At the very least, you shouldn't need me to give you turn-by-turns after telling you to take this route across the city.
I'd say 75% at least ask if I want to take Rock Creek Parkway (though yesterday, one got lost and took me to Virginia...) These are old guys who hang around the Kennedy Center/Watergate all day. I'd say it's flipped for ride-sharing services, where the driver almost always relies on the GPS (I take it Uber's GPS isn't very good--Waze suggests the correct route).
I've noticed this on multiple occasions: Uber has pretty terrible built-in GPS. It almost always has my drivers taking the larger/busier roads even though they are less direct and more congested than side streets. It's like when Google Maps gives you the three possible routes, Uber often picks the equivalent of that weird third route that makes no sense.
