Ratan Tata, the Henry Ford of Mumbai, just revealed his dreamwork here, the Tata Nano, to a European audience here at the Geneva Auto Show that may never get to drive one. The micromini β€” which, in person, appears to be two scooters sheathed inside an extra-large Maytag dryer β€” is for now just for emerging markets where safety regulations are far less stringent. The price is 100,000 rupees, which is a mere $2,500. That's cheaper than some scooters, and you only get one! Nonetheless, Tata says he's repaying Geneva for its hospitality 11 years ago when he was a paltry millionaire and his car company was just a fledgling. Now there are four million Tatas on the road, and soon to be many millions more of this microbox.
