Thanks for the link, brings back some interesting memories. One of my business trips to India involved a lot of driving between sites, five or six hours some days - seen some crazy things.
At first I would just smile at my colleage through fear, but amazingly you get used to it fairly quickly and end up relaxing and laughing as a ten ton truck is coming straight at you frantically flashing it lights and hooting..
I got really sick on one trip, so the driving was the least of my worries. I would still go back though.
