Hallo Raghunathan,

maybe I should concretize my statement:

"If I find a car driving constantly at a suited speed, I do either follow him at constant distance, or I will drive in front of him, also at constant distance."

It's not so, that I search for a car driving at my speed. It's more so, that sometimes, if you are on a longer trip on highway, you notice, that there's another car driving at nearly same speed. And after a whole series of overhaul manoeuvres (puh, what a word...) I find it suited no longer to overhaul him, and he finds it suited no longer to overhaul me. Finally we drive in a column with nearly same speed, sometimes over dozens of kilometers.

This defensive sort of driving I choose especially if children are in the car. Then I often decide to limit my speed to certain level. Mostly it can be seen, that in the 'mirror car' also a family with kids is sitting...

By the way, I do also like Terry's point of view. Isn't it amazing how much psychology plays a role when doing so simple things like driving a car? We humans are 'group animals' and we like it to be part of and to feel like a group...

Bye,
Kai
