Seven years ago I got a taxi in Las Vegas to go from the airport to my hotel. The whole ride had ads blaring from the radio and the backseat area was filled with display ads. I’ve never taken a taxi since then. What you describe will be a thing in the U.S. if self driving becomes a thing. We already can’t get gas without being bombarded with ads. To me this fact is the main reason I hope to get an electric car someday.
