I agree that Musk and other proponents of transportation innovation could do more to support the efforts of their municipalities by promoting walking, biking, buses, etc, but that seems like a poor argument against pursuing innovative concepts. Musk's propositions should and will coincide with years of statistical analysis before actual implementation to prevent exactly what you're talking about. Hyperloop could be to the detriment of a lot of cities, but that doesn't mean there aren't implementations that can improve transportation time, congestion, and quality of life. The attitude that pursuing futuristic transportation technologies will hinder ALL cities seems detrimental to human progress. What brought about our "proven" public transit systems, like subways, to begin with? Developing Hyperloop or the Boring Company doesn't need to mean replacing current infrastructure or stopping municipal efforts. It means we could put our brightest engineers towards some of humanity's most annoying problems (https://www.wsj.com/articles/SB913090787638355000 https://www.wsj.com/articles/SB913090787638355000), forcing them to pay attention to municipal data along the way. If analysis indicates that tunnels would be detrimental to New York, then by all means, let's not build tunnels in New York. But if other analysis indicates that Los Angeles, a city incredibly dependent on cars for transportation (http://www.smithsonianmag.com/history/nobody-walks-in-la-the-rise-of-cars-and-the-monorails-that-never-were-43267593/ http://www.smithsonianmag.com/history/nobody-walks-in-la-the...), might actually benefit from such an idea, we should pursue it. Don't be so quick to reject an idea before proper analysis has been done to understand the impact. It's the innovative ideas that end up actually improving humanity, and believe it or not, a lot of the things we consider to mundane today, sewers, subways, roads, skyscrapers, were at one time innovative and new.
