I have had drivers do stuff like the OP describes. Once in downtown Atlanta traffic I had some guy screaming at me cause I passed him on the left cuz he had made passing him on the right impossible because he was so close to the curb.
The weirdest incident like this occurred in Cades Cove in the Smokey Mnt. N.P. This is a scenic loop that can get really jammed with cars when the bears or such are showing off. Had a Winnebago try to block me from passing him on the right and the guy started blowing his horn when I got around him.
Sheesh it 's not your fault the're not going anywhere fast...
