At the edge of a tree-lined lane in Mumbai, India, Abdul Kareem opens the hood of his taxi and pours water into the radiator. The car is black with a yellow roof, like all Mumbai cabs. But it stands out in a line of cars.
It's antique-looking and kind of boxy, with bulbous headlights. It has a metal luggage rack on its roof that proclaims "Mumbai" in bright orange lettering. On the streets, Kareem says, people point out the taxi to their kids.
