"It will take longer to get through security at O’Hare than it will take to get to O'Hare," Emanuel predicted. "This is the fast lane to Chicago’s future." Boring Company says it will pay the entire cost of building the system. The company indicated in its proposal to the city that fares on its transportation system of the future – although not yet set – would cost more than the current $5 fare between O’Hare and downtown but less than the cost of a cab ride, which typically costs about $40. The deal puts Musk a step closer to making his Boring Company's vision a reality. Mass transit advocates have expressed skepticism about the viability of a vast network of underground tunnels due to high costs and bureaucratic hurdles. But Musk’s tentative deal with Chicago suggests that his company may be making progress in its goal to reduce the price of tunnel digging while increasing the speed of the notoriously slow process. “I think if you look at someone’s track record or a company’s track record…it’s reasonable to extrapolate into what it would do in the future,” Musk said about criticism of the effort. “I’ve done a few things in my background that I think are pretty tricky.” Musk added: "If it succeeds it will be a great thing for the city. If it fails, me and others will lose a whole bunch of money."
