I have a number of questions I'd like to ask you (and other drivers using these services). I can't think of any reason why it'd violate FT terms for you to give factual, polite answers based on your own experiences. I think the bigger concern would be whether any of the services you contract with have required you to sign strict non-disclosure agreements. If you feel comfortable answering questions about your work in the open I suggest you start a separate thread entitled something like "Ask a Uber/Lyft/Sidecar driver", similar to past threads we've had for Q&A with airlines employees.
