Tesla denies in a blog post, lol!. But the wordings in the agreement says something else. It specifically asks to keeps the incidents confidential. No one outside this forum of rabid fans have any difficulty understanding that this is an NDA. NHTSA did not have trouble understanding it. if not from NHTSA, then from whom did Tesla try to hide the defects & issues? From potential customers who their customers refer? Mr. Musk is the master of excuses when caught red handed.
