I got my class D DL in '58......drove commercially for over a million miles in a several year period starting with a chauffeur's license....then a commercial chauffeur's license ....then grand fathered to a class A CDL during the change over. We've always lived rural so lots of highway miles....like 660-680 miles a week commute for many years.
Agree with others about some drivers are clueless of how to drive safely. I see that when we get near a large city or in certain parts of town or a certain expressway or a major city street.
One of my water district board members is a just retired state trooper. He says just in his 27 years, as a LEO working mostly traffic, the department says the last 10 years or so there has been a marked increase in fender bender accidents caused by mostly careless young female drivers in particular on/off ramp situations. They think they can turn their signals on and change lanes without looking.
IMO from experience following to closely goes to that age gender also. Scare the hell out of me when you check the rear view mirror and all you see is the top of the car under your tail gate. Finally the car passes me and yep...there she is putting her lip stick on...or one of her hands stuck in a ear.
