[edit] unless his real plan was to go to China all along...
If he couldn't answer these very basic questions 2 months away from shipping these things, WTF is he even doing. If he hadn't proactively initiated communications with NHTSA long before now, WTF is he even doing. These are all excruciatingly, painfully obvious things to do, and the fact that it never occurred to him to do them brings into question his judgement about pretty much everything, from technical issues to basic life choices. At this point I don't think I'd trust this guy to mow my lawn, much less develop autonomous vehicle software. His reaction to all of this and how he deals with adversity is just as revealing about his competence as everything he's done so far.
Trying to innovate without being encumbered by the glacial pace of government regulatory bodies?
His refusal to put up with the NHTSA is an indicator of a low tolerance for bullshit, not incompetence.
Double so if it's a product that is very likely to kill its owner.
And square all that, if your products is either used every day or can cause large amount of death, accidentally.
