There are bad drivers everywhere, to be sure, but driving the same speed in all lanes seems to be a style of driving here. Maybe no one is in a rush...idk. As someone who drove most of my life elsewhere that now lives here its extremely evident to me.

You can say it's out of staters all you want , but this is decidedly a MA problem and it's pervasive. Very often the right lane will be empty with a long line of cars in the left. Infuriating.
