I'd be pretty damn actively aggressive if someone was trying to make me apologize for manufacturing a car that kept its occupant safe in a 110mph crash.
Who? A PR drone who would say much while communicating nothing, and do so in the most boring, robotic manner possible?
Normal people don't spend their time thinking about how much more they would like it if an executive's statements conformed to the PR industry's self-serving standards.
The industry is full of non-personal appeals. One that's personal and stays personal even if it's a bit defensive, is just more authentic and appealing.
Besides who reads these? I doubt a large percentage of potential buyers do - mostly likely already fans of Tesla, who probably agree with Musk anyway.
