Last night I picked up my son from the last session of his summer classes at Salem State College. On the way home (driving at night, in the rain, with mucked-up lenses, yeah), I was trying to pass some cars in the center lane. Unfortunately, the car ahead of me in the passing lane was not cooperating. It was being driven at erratic speeds, sometimes up to 75 mph, then drifting down to nearly 60 for a while, then speeding up again. Other cars were passing us by dropping into the right-hand lane and swerving around us all, but, eh, that's not the way to do it. I wasn't being pushy, I wasn't tailgating (which (1) I don't do, and (2) would have been exceptionally stupid given the erratic speeds), I just waited, and eventually the car did pull enough ahead of the center cars to move into that lane itself. As we passed, my son looked over and saw that the driver was talking on a cellphone and had a GPS screen lit up on the visor.
I'm generally at least somewhat sympathetic to people trying to find their way through the convoluted road system in and around Boston. Especially at night. Especially in the rain. But dammit, that's not what the left lane of 128 is for.
