To help give a bit more clarification, Seattle doesn't get snow or ice very often, and if we do, it is usually gone within 24 hours. However a few years ago Seattle had a massive ice storm and all the road reflectors

were "popped off" when the scrappers (that usually only service the mountain pass that divides WA) came over to scrape off all the ice. I do agree that it is a never ending process, however advancements in paint quality and application, have greatly reduced how often this needs to take place.
As for your last point... are you saying transportation is a dying industry?! So how does one get to their job site to do construction? Or a legal team get to the court house? or medical professionals get to hospitals and urgent cares? or the trucks that ship of all your goods? Do you know of further advancements in teleportation that I don't know about?
Thank you for the reply and allowing me to explain more. I am interested to hear what you have to say regarding the industry.
