Where are you driving?! If the person you're replying to has gone 8 months in Boston without having to intervene, I'm impressed. Boston is the craziest place to drive that I've ever driven.

Pro tip if you get stuck in a warren of tiny little back streets in the area. Latch on to the back of a cab; they're generally on their way to a major road to get their fare where they're going and they usually know a good way to get to one. I've pulled this trick multiple times around city hall, Government Center, the old state house, etc.

Or when. Driving during peak commute hours really makes you a sardine in a box and it's harder for there to be intervene-worthy events just by nature of dense traffic.
