Yes, I have this same issue. I avoid confrontation as much as possible because of it. It frustrates me so much that I can't muster basic words in a situation like that. For instance, I was pulled over in the Spring for being in the passing lane on the highway with no cars to pass. When the cop asked me why I was in that lane I just quickly said, without even thinking, "passing" - it WAS true, I had just passed a car who exited just a quarter mile or so before the cop saw me. The reason I stayed in that lane after passing was because the highway was about to end and I needed to be in that lane to turn in town coming up. Of course my stupid brain completely dumped that tidbit and I didn't mention that. When he confronted me on the fact that he saw no other cars, just me on that stretch of highway, I froze and couldn't say anything else. I'm sure this made me look like a liar. I tried to explain it on the appeal form online, but of course they didn't buy it and I still had to pay the full fine and pay for traffic school to avoid getting points put on my license.
