The intersection of Cedar & Terrace Streets (halfway between Roxbury Crossing and Jackson Sq. stations). It's a relatively new stop sign—within the past year—so some unobservant drivers still run right through it. I've nearly been hit at that intersection, on my bicycle, a number of times by thoughtless motorists in a hurry, often with their heads down, distracted by their mobile devices—a potentially lethal combination. 'Head's up!' everyone; and i mean that literally. Kindly get your faces out of those phones. Thanks.

I've always thought every stop sign in Massachusetts is ignored.

South Street in Roslindale.

How about High and School Streets in Ctown, I'd say 1/5 of the cars blow right through that one.
