An incident like this prompted me to get my CHL. Similar situation, but in College Station. Was on a service road that narrowed from 2 lanes to 1. Apparently a guy in a big King Ranch F-150 thought I cut him off in my little Pontiac
. He floors it around me on the shoulder and brakes HARD in front of my car, blocking my escape. Gets out, comes over and tries to open my car door. When that doesn't work, he hits the window and screams at me to get out of the car. I yelled back "no!" and he gave up, got back in his truck and drove off.
It was an enlightening experience. I'm not a small guy, over 6' tall but this guy was bigger than me and mad as heck. I'm just glad my car locks the doors when you put it in drive, or I might have had a pretty rough day.
