Mexico Grid Penalties...

[Scott]

In case anyone was wondering, both Macca's and Gasly.  What a shame.

Throw Ricciardo into the bunch as he has also changed an engine.

Poor Gasley, inheriting a penalty that isn't even his.

Now, given that the penalties are applied to the car, not the driver, what if it's a close championship and the leader has to change engines, but his teammate still has one available... can they swap cars?  Obviously this violates the spirit of the rules, but we know that F1 means driving right through loopholes.

I'm sure there is a rule that ties the driver to the car for engine/grid penalties.
