I think it's a recent phenomenon, though I can't think of a reason for the change.

Since I came back to driving trucks I have noticed a distinct lack of simple common courtesy and professionalism amongst my fellow drivers. My working theory is that all the “old hands” have retired and the current crop of drivers don’t know what it’s like to get yelled at on the CB for doing stupid stuff.

Plus they will let you train new drivers with only six months experience which isn’t enough. And the multitude of people from other lands where driving rules are basically “the largest vehicle has the right of way” who I see all the time running up a few feet off a car’s bumper going 80+ mph.

I don’t even think I’m falling victim to the “get off my grass” syndrome, these people are just idiots.
