I think it will be soon because there is a huge number of markets to test in. You have every state in the US, every country in the world, and a dozen players all working on it. In an n*n space, you just need one technology+municipality pair that says "ok, we'll risk it" and you have a very public, newsworthy demonstration. If there are real benefits to the tech, it will be impossible to keep them off Instagram. From there, it will spread to opportunist governments... Places who will try anything if it draws interest to their municipality. At some point after that it becomes a liability to not allow it. Now, how long before each of these stages? I don't know, but there's pressure there.
