The requested things are pre-existing regulation requirements, simply worded with leading questions to prevent unnecessary back-and-forth.
For one of many examples, public information seems to show that his device affects the rear view mirror in a manner that violates specific pre-existing regulations, they ask him how does it affect the rear view mirror and how does it comply with those regulations.
There are only two reasonable responses for such a question - (a) he submits the evidence he has (and had before receiving that letter!) that his product is compliant with these regulations; or (b) he acknowledges that right now he cannot demonstrate that the product is safe and will not sell the product.
For such devices, documentary evidence (including testing results, and all other "random crap" requested) is an integral component of the device - if you don't have all this done, attempting to sell the product is prohibited. That is pre-existing regulation.
