When I saw this cab ahead of me on the road I did not make the connection. I figured out that Gregory David Roberts is Shantaram only after I googled. I bought the book some years back, and found it was a great story: an Australian on the lam comes to India, begins to live in a slum, blunders about before beginning to work for the Indian mafia. The story’s probably mostly made up, but it is wonderful stuff, worthy of three movies at least. It was interesting to find that tourists might want to follow a Shantaram circuit while in Mumbai. Of course, it would lend a cachet to the experience if you were driven by a friend of Shantaram.
The 6+1 probably means that the taxi can hold 6 people and the driver. It would be a bit of a tight fit, I think. The words below the wheel of Dharma (Dhammachakka) say "Jai Bhim", a slogan used by neo-buddhists in their rejection of caste.
I wish I knew what Bindra means. Is it Bandra mis-spelt? Is the driver a friend of reality TV star Dolly Bindra also? Or maybe of the first Indian Olympics gold winner, Abhinav Bindra?
