1) I think most of the resource sharing is driven out of cost necessities. There are many places where people share a single autorickshaw to the same destination. This is sometimes because there is a shortage of taxi/autorickshaws/bus availability at peak hours. I tried Uber pool a couple of times in Mumbai and almost always travelled alone. Not sure what's the reason.

2) The status still exists. However it can be practical to not own a car as roads are extremely congested in big cities (in some places temporarily worsened by public transportation infrastructure projects)
