> I open up Uber and tell my destination, and Uber tells me 87₹.
If the network is down, your Uber isn't going to open. Yet you can hail a cab and pay with cash (or credit/debit).
Your taxi experiences are probably very different from mine, but getting scammed by a taxi driver is very unlikely where I'm from. And in my experience everything runs like clockwork in Denmark, I'd expect the situation to be very similar there.
Taxi services across the world are very different, so your experiences might be as valid as mine. But where I'm from, Uber doesn't provide anything that a normal taxi service wouldn't.
In contrast, a traditional taxi meter allows the cabbie to take a circuitous route with unsuspecting passengers. Before Uber I needed to constantly be on guard against autowales doing this to me (due to my ethnicity I'm prime ripoff target).
