This is not meant to be disrespectful, but it looks like you have not yet traveled to a location where Uber offers a service that is very different from the one they offer where you live.

I live in the US, use Uber, and have used Uber in India. The service offerings were very different in the two countries. I was glad that the same Uber app I used in the US, connected to my credit card, works well in India without needing a new app to be installed.
