The joys of idiot drivers

I knew I was back in Massachusetts when I drove to work this morning. Very quickly I was back in reality - and behind idiot drivers.

So I am driving down Broadway near Soundbites this morning and I am approaching the light at Willow. As I am approaching there is a minivan that is slowing down at the green light and comes to a complete stop. And sits there. At a green light. I am far enough back still that it makes no sense to beep. As I continue to approach they continue to sit there. Then the light turns yellow. Still sitting. And then red. Still sitting there. WTF!? Who stops and waits at a green light?

By this time I'm behind them at the red light. Then when the light turns green they went. So there appeared to be absolutely no reason why this person just stopped and sat there for no apparent reason. No one got out of the car, or in. It's just baffling.
