tadu, like what Rahul said, being on a Scorpio helps make the road, very few want to take a potshot at me, especially when they see all the scratches and dents in the body!!
I am not submissive either, just that I do not waste breath in swearing, stopping and arguing, etc. On the road, anyone trying to act over-smart - overtaking from the left in a 2-lane road, honking unnecessarily from behind to overtake when there is no way anyone can overtake, swiping me in the front, etc - then I also settle down and deny him what he wants. However, I am very careful in doing anything of that sort when I am out of my home territory, don't take "punkhas" when I am on a long-distance highway drive, let him do whatever and get away with it, not worth spoiling my trip being an "activist" or doing a "I will show you" tantrum. However, I do indulge in speed runs to beat him off, which I achieve mostly by what I call "tactical" speeding, which means I manouevre better than he - invariably, I manage to outsmart the guy that way instead of simply driving brashly at high speeds.
