I had come up with an idea for a sign to post around town announcing that Uber is here and explaining how to download the app, etc. It would have tear-off strips with promo code. I had come up with some Dr. Seussian language: "We can take you here or there, we can take you anywhere ..." I posted this on my local drivers Facebook page and someone said this was verboten. Is that true? Seems to me that Uber would want us to solicit riders, especially in a new market like ours where ridesharing is just taking hold.
