>> If a bunch of other journalists replicate the trip
Is it really a replicable test? They'd need the same weather patterns, traffic conditions and the same car (untweaked or modified since Broder's drive), not a different, "equivalently equipped" model.
In the documentary Revenge of the Electric car, there's a scene where Musk walks into a warehouse full of cars, all having different issues preventing shipment. For all we know, there was a problem isolated to the particular car Broder drove AND, at the same time, Broder was embellishing his story. In other words, the truth is somewhere in the middle.
Of course, we'll never know because we'll never get access to the raw logs.
