why do some drivers tailgate?

Didn’t read through. Some truck drivers are awful.
Just this morning. Had a truck come up on me on freeway. This was a Supertrucker truck. Mechanical. All kinds of lights and such. Slowly changing lane to pass. He came up close to my trailer on the line. I just pulled off onto the shoulder and hit the brakes. Let him involve somebody else in his wreck.

 

Had a Pete roll up on my F150 this morning, just slid my back window open and tossed my morning coffee with butter out the window, so theroy is if it hits his windshield he's to close, yup he was too close so I added a bag of all purpose Gold Metal Flour out the window, yup that landed on his windshield too, hmmm them he headed for the shoulder. Maybe when the back of the car your rolling up ondispears under your hood your too close.
