No smoking guns I suppose, but there's a fair amount of suggestion at trying to trick others.
Elon's biographer for example is on the record saying he's convinced that Elon disingenuously proposed Hyperloop and created Boring Company to spread FUD and try to weaken California's high speed rail project and other public transit proposals.
Relating to criticisms of the Boring Company and his theories around transportation, Musk is on the record himself of asserting that Induced Demand doesn't exist which is a pretty remarkable statement considering that it's effectively an uncontroversial proven fact in transportation planning circles.
So at the very least, in asserting that the entire profession is dumb and wrong he is suffering from delusions of grandeur that he is smarter than he actually is.
