" most aggressive, impatient drivers" That could describe me. But as you've witnessed what really scares me is the tourista that cruises along at 10mph below the already conservative posted speed limit.
You know their minds are not thinking about the task at hand namely driving. They are usually day dreaming or counting the leaves in the trees or the animals in the woods! Or worst yet thinking about the itch in their shorts. Then all of a sudden without warning they brake and make a left hand turn. The traffic behind be damned.
