Elon Musk’s Boring Company, a project that plans to use futuristic underground pods to transport cars across long distances without traffic congestion, is starting to take shape.

Fresh from raising $300,000 from the sale of hats — an ‘initial hat offering’ — and getting permission for projects in Maryland, Musk has confirmed that the company will bid on a project to link downtown Chicago with O’Hare Airport.
