Uber keen on launching shuttle services in Bengaluru after Delhi, Kolkata and Hyderabad. What's stopping them?

The cab aggregator Uber aims to launch bus shuttle services in Bengaluru to improve the mobility conditions in the tech capital. After launching the idea in Delhi, Kolkata and Hyderabad, Uber is now looking to enter Bengaluru with a similar idea of ferrying large numbers of people from one place to another. However, Karnataka transport département is yet to approve the idea as the government policy only allows state-run BMTC buses to operate within the city.
