The problem text based interfaces solve is a lack of UI standardization. In a desktop environment a command line can be superior to some designer's attempt to express herself through a fancy GUI. However, key strokes on mobile are MUCH more expensive than in a desktop environment. What would have been a 4 second interaction on a desktop might be 20 seconds on a phone, simply because typing is slower. What this needs is a minimalistic UI for executing commands that doesn't involve typing. The workflow would look something like this: Unlock phone > tap Uber > tap destination > tap execute > lock phone.
