Elon Musk seems serious about creating a boring company to solve traffic

Tesla and SpaceX founder Elon Musk has a pretty good sense of humor, but sometimes we can't tell when he's just joking or mulling his next big idea. 

For example, on Saturday Musk took to Twitter to say out loud what every traffic-plagued Los Angeles resident is silently screaming inside: The city is a gridlocked hellscape.  

"Traffic is driving me nuts," wrote Musk. 

But he didn't stop there. He also raised the idea of boring through obstacles to alleviate traffic woes.
