I think there are two sets of burdens of proof here. The engineer who made this decision has a burden of proof to his boss (and maybe regulators, don't know) to show that this is safe. The random internet commenter suggesting it is unsafe has a burden of proof to show that either it is actually unsafe, or that at least that Tesla didn't internally meet it's burden of proof.
