Cokes Brand was built on mouth feel, ie once someone develops a preference for Coke, they are generally immune to switching sodas. Coke did a ton of marketing to reinforce hat.

Uber’s moat is built on its brand as well, not just the massive awareness of their services, but the fact so many people have their app, and they have the most drivers. More drivers makes the customer experience that much better.

Just looking at app installs, it will take Lyft years and will cost hundreds of millions just to catch Uber in US app installs.
