The DC area is one of the most stressful areas in the country to drive, along with NYC and LA. The lanes are narrow once you get into the city limits, and accidents are common. But everyone in the area knows and dreads the beltway during rushhour. It's usually extremely congested but to make things worse, other drivers drive extremely aggressively and you are constantly being cut off. Has anyone tried the 2nd gen autopilot in the DC area (or NYC or LA) during rush hour? I see a ton of Model S's on the beltway so I'm curious how it performs and how often you have to intervene. And yes, the Model S's cars usually are driven very well. It's usually some guy in a Mercedes or BMW that is cutting everyone off. Is the drive less stressful?
