Why are there so many fatal car accidents in Mass?

Massachusetts has the fourth worst traffic in the world and part of what makes it so bad is the high rate of traffic fatalities.Other developed countries (even ones with terrible traffic), such as the UK and France, have far lower fatality rates. Why is this? asked the Boston Globe recently.Yonah Freemark, of the Urban Institute, says that larger US vehicles (SUVs and trucks) and poor road and sidewalk/bike lane designs are to blame.The Massachusetts legislature works at a snail's pace, according to the Globe and it's going to take major changes to decrease the rate of fatal road accidents.
