Re: Safety-critical updates?
Logical conclusion - as soon as manufacturer is aware of a flaw that will require a safety-critical patch..
This is exactly the current system with aircraft.
The manufacturer can order immediate grounding until the fix is applied, or it must be applied within n days or at the next service interval - depending on the severity.
If there is a recall on your current car it doesn't mean you need to be constantly on the NTSB's webstie and screech to a halt as soon as a safety notice is published.
