Uber has introduced ride-sharing in Chennai, the sixth Indian city and 29th globally for the San Francisco-based cab aggregation platform. Uber is locked in an intense battle with homegrown peer in India–Ola, which has confirmed that it has tied up with automaker Mahindra & Mahindra to help about 40,000 drivers become entrepreneurs by 2018. While Ola has aggressively expanded and taken the early-bird advantage across categories and geographies in India, Uber has had a measured but progressive expansion plan. It now has 4 lakh drivers across 28 cities in India. With the merger with Didi Chuxing in China, Uber can sharpen focus on another of its large market in India. UberPool, says Bhavik Rathod, heading West and South for Uber India, is a hit in all the five metropolises launched over the last year. About a fourth to fifth of all rides on the platform in these cities are pooled orders.
