I travel to India, a lot, as I have family there.
Pre-Uber days, here's what it took to get an auto-rickshaw (also called "auto"): you walk up to the "auto stand" where you see some auto drivers lounging. As they see you walk up, they size you up; and immediately jack up the prices they're going to quote you as they see you don't seem a local. If you turn one of them down, the others will simply refuse to talk to you or even look at you. Then your best bet is to keep walking, looking for an idling auto driver.
Post-Uber world: pull up the app, enter the destination address, and watch as the car approaches your location. Hop in, driver is incentivized to get you there as quickly as possible. Hop off at the destination, give him 5 stars, and you're on your way. Simple as that.
For me, Uber was always an essential service in India.
