It seems that motorists are not cognizant of the things that are going on around them.
When you come to a stop sign, you are supposed to come to a full stop before the crosswalk, not halfway to three-quarters into it. Some people just slow down and continue to go right through it without looking.
When pedestrians have the walk signal, motorists who have the green light are supposed to allow them to cross the street before turning into the intersection. I recently someone to cross the street, and the idiot behind me suddenly swerved around me and nearly plowed into the person crossing.
There are more motorists driving around today with their brains in their backsides, and who use no common sense. How they ever got their licenses is a wonder.
