Hi velma929,
Yes, I've heard those comments at times, too. I can think of times when I was drinking alcohol, and later taking opiates, that I drove my car without any qualms that I was not doing the right thing. My own behavior was unacceptable, and I did not even think twice about it at the time.
Thank you for not getting irate at my knee-jerk response to your post. Now I wish the drivers on the highway would behave as politely as you just did with your response.
