Help! Dog Tracking!!

I am not disputing your claim, I trust you know what you are talking about. I am at .41 degrees positive thrust angle which isn't too much, just a little off zero. I went for another cruise tonight and had my friend drive down the centre of the highway and I could see the passenger front tire from my vantage point but not as much as the drivers side when following behind in the correct lane. It is true that the front wheels are set apart wider and that just proved it, and I measured also. So I am looking at a small correction and an illusion when being followed. Not too much to worry about, just enough to bug me!
