I'm thinking The 'ol Tesla Trail was always an ingenuity example (and the state pandering to Tesla, honestly). We have something called Calici out here that makes drilling an underground like going through solid concrete, because Las Vegas was the bottom of a lake for some period of time.

As a local, kind of hoping that the urethra between the ends of our very large convention center area becomes the proof of concept for what we desperately need, rapid public transport to the urban areas. The Regional Transportation Commission does the best they can with busses, dedicated lanes, regional transfer stations, but it's still a city you can't exist in easily without a car.
