If anyone is actually interested in how public inquiries (on any topic) currently work and the shortcomings of the system, the Lords Statutory Inquiries Committee presented a report into that topic in September
https://committees.parliament.uk/committee/702/statutory-inquiries-committee/news/202927/failing-to-follow-up-on-public-inquiry-recommendations-risks-avoidable-mistakes-being-repeated/
There have been 18 public inquiries last year - Grenfell, Contaminated Blood, Covid 19 response, Post Office Horizon Scandal and Lucy Letby would be the most high profile. Any one want to guess at the others?
The report conclusion:
"But too often inquiries are failing, chiefly because when they report there is no obligation on government to act. It doesn’t have to give reasons for rejecting recommendations. And if it says it accepts them, there is no systematic means of monitoring implementation. Inquiries cannot themselves pursue government because the moment they report, they cease to exist. Hopes raised by the outcome of an inquiry can be dashed by government inaction"
There was an inquiry into the rape gangs.
A better focus would be on ensuring all public inquiries have their actions points and recommendations followed up on. Otherwise any future inquiry would also have potentially little actual impact.
But I doubt Elon and his gormless supporters have much interest in actual policy and implementation, just hoping to blow some dog whistles and get the racists riled up.
