All the time. In the car, too. For some perverse reason, drivers in MA think that the person driving (or riding) on the straight road, with the right of way, should slow down and stop for those turning and/or entering. Perhaps it's done in guise of being polite, to let one person in a line of traffic, but it makes for some *very* confusing situations. I usually try to stand my ground and if I am the one being waved on, I stop, unless the coast is really clear. People, in general, don't know what to do at intersections or merges. Four way stops, forget it. If one car is stopped at a 4 way stop sign intersection around here, he or she generally *waits* until all cars approaching are at the sign and stopped and then there is a guessing game as to who goes first. Quite dangerous. I am not sure what happened to "the one who arrives at the sign first, goes first rule" I learned in Florida and Arizona. It seemed to work fine there.
