I am just wondering if there are rules that force a damaged car to pit in case it can be source of debris? Today it looks a lot of debris was being spread periodically by cars involved in some incident earlier on. For instance Vettel's AM looked like a distributor of it after that collision with Tsunoda. Similary Hamiltons Merc could have further spread more debris after that tag with Verstappen.
I remember back in France '07 Kimi Raikkonen kept driving his Ferrari after a part (cannot desribe) kept hanging and neither Ferrari pitted him nor race control warned Ferrari to do so. Such parts can cause easily a '09 Hungary type incident with Massa.
Why is it that such safety critical situations are not capture by race control? Are there any examples deeper into the past where cars were forced to be retired because they could be a source of hazard?
