In Tamil Nadu, a 1000km race has begun using autos! An auto (auto-rickshaw) is a ubiquitous form of transport in India, it's basically a two stroke engined vehicle, with a roof, open to the elements for the most part, very loud, not tremendously comfortable.
From the race website:
The race will take you deep into the heart of Tamil Nadu. Once there you'll travel through an incredible course of misty jungles, balmy coastlines, flooded streets, monsoon rains and overpowering Indian crowds. By reaching a multitude of challenging waypoints and completing physical and intellectual exercises, you may be crowned Autorickshaw Rally World Champion.
