To be fair, those students are contending with people driving in and out of Boston. The odds are not in their favor.
Edit: well color me an idiot, I just checked and a 2019 usnews report had boston as ranked 3rd on worst drivers, based on whatever set of variable they came up with, so touche.
One other thing to note is that two of the _other_ top 10 are also in Mass, Worcester and Springfield. That's the only triplet on the list in the same metro area.
Though I guess, for the point I was making, it doesn't matter if Boston driving is the actual worst in the country or not, as long as it's very bad, which I promise you it is.
