Billionaire Elon Musk claims to have made $300,000 in hat sales for his tunneling venture called The Boring Company.

Musk founded the tunelling firm after becoming furstrated with traffic in Los Angeles. His idea is to build a series of tunnels under L.A. with cars ferried around on pods at around 125 mph.
