Yes I have traveled to places where I don’t speak the language, need to get an Uber at a specific place, and need to read the signs. You can get surprisingly far if you know a few words in the local language, and in your hypothetical future, even if you and the driver have an agent, what are you going to do if you need to communicate with someone in person that’s not that driver? Ask your agent to? I don’t see how that’s a feasible idea.
