Agreed, if by random check they found 2 of 4, they should do check all the grid. Jezz
Imagine this was some sort of safety check, and after finding 50% of your sample faulty you just stopped checking. Well done F1.
But it’s not a safety check. Its a technical rules check. They applied the rules as they are written, is this not what everyone wants? If they randomly changed the rules in order to DQ more cars, that would be an outrage. I think a lot of F1 fans need to actually think about what they they are asking for.
Plenty of things in F1 are random checks. Weighing the cars during quali is random. The randomness is enough of a deterrent that teams do not run cars below the minimum weight. But things like plank wear should be checked for all because the teams cannot accurately know how much the plank is worn especially on sprint weekends.
The FIA can’t check every car on the grid for every single rule in the regulations. It’s not practical, and is a waste of time and money.
Random checks are fine, but if it’s something that can affect all cars then they should all be checked. So for plank wear, if 1 of the 4 fails, all 20 cars should be checked.
If the drs wing opening too far is checked and failed both of the cars from that team should be checked, as that’s unlikely to apply to the other teams.
