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, and then work for the Indian mafia. 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?
