I spotted this LC heading north on 495, somewhere between Tyson’s Corner and the Potomac River. You might be thinking, “wow, there’s so much empty space in what presumably is DC area rush hour traffic,” alas, this was but a momentary gap that formed.
One nice thing about the highways around DC is they’re surrounded by lush trees. So at least for a good part of the year you have nice scenery while sitting in crushing traffic.
