Changing tyres under a red flag

[lolzi]

So with these "new rules", the team boss might command his drivers to run into each others' tyres enough so they can be deemed broken?

I do prefer the simple approach, and the NASCAR red flag rule seems what I would like.

The red flag means that all competition must stop. This not only includes the drivers on the race track but also the pit crews. If the crew is working on repairing a car in the garage area then they too must stop work when the red flag is displayed.

No one gains any advantage, not one is unjustly penalized, everything just stops.

One of the few things NASCAR does right...

Interestingly IRL allows repairs to be made to cars between a race being red flagged and then restarted, which can be on different days if an oval race has been stopped due to rain.
