Pedestrians in MA jaywalk routinely. Especially in the city. Many times, I am the only one at an intersection in Boston, waiting for the walk signal.
However, once you get out of the city/close in suburbs, I would say the majority of drivers stop for pedestrians in the crosswalks, waiting to cross. But some people are clueless.
Yesterday I was driving through Concord center, in a spot where I rarely drive. It was really congested and there were tourists everywhere, cars pulling in and out of spaces, cyclists, delivery trucks. There are 3 cross walks within a 1/4 mile stretch of Main St. I was in a long line of stopped traffic, waiting for people to cross. There was a UPS truck next to me, stopped at the curb on the corner, unloading. When I went to go, a guy walked right into the crosswalk, in front of the truck, and I could not see him approaching . I had to slam my brakes. I was shaken, especially since I ride through the same spot much more than I drive and kept thinking, what would have happened if I was on my bike?
