A disastrous failure worth $6b! That's my point. Neurolink and SolarCity are also disastrous failures. But Boring Company has gotten contract in Las Vegas, Chicago, LA, and more. And despite all these failures Miami, amongst a few other FL and CA cities, is still in talks about a contract.

That's the business. Continue selling a dream. Talk to any actual engineer with relevant knowledge and they'd likely tell you it was a terribly thought out idea from the start. But those engineers aren't the ones signing gov't contracts
