Speak screen saying "one dollar?"
I can't really get the code of the web page/app, but checking older/similar JavaScript/PHP code of uber.com it seems to be a hick-up of the Text-to-Speech framework which probably stumbles over a snippet similar to ..."common.step-to-main-content":"Skip to $1"... with $1 being a positional or a formal parameter with the "value": main_content or main content.

The above code (without $1 but with main content) can be found in uber.com/drive/new-york/ (Google Cache).



I'm no coder so I might use the wrong terms...
