That website needs an update. He did deliver a pick-up truck (though that was neither a better truck than the F150, nor a better sports car than a standard 911, like he promised).
Time blindness is a well known common symptom of autism, which he has openly disclosed having. Anyone dealing with time estimates from someone with autism and time blindness should simply adjust for this known attribute of their being instead of relying on or attacking them for their disability.
He doesn’t get a pass when it comes to time-related criticism of him if he doesn’t also afford the same pass to his employees and the regulators of his businesses.
Some other reviews state there is evidence, but only on studies for very small time scales. Not saying this definitively states anything, but it is interesting.
