I was passing through there recently, blinker on, waiting to make a left onto Route 9, when the driver behind me did the kind of crazy thing you see at this intersection - and all over the Boston area, with its many irregular junctions and short-tempered drivers. As the last oncoming car cleared and I began to turn, the driver behind me stomped on the gas and tried to squeeze past me on the inside. There wasn’t room, of course, especially for her wallowing SUV, and to avoid a crash I swerved wide, narrowly missing a car on the other side. She had taken the kind of insane, pointless risk with both of our cars and lives that briefly fills even a gentle woodland creature like myself with hot outrage. In a moment like that, you run through your options for decisive response and then realize, already cooling off, that there’s nothing you can really do.
