I get all the above objections, but I just can't see past Tanak being able to stay in the event.

So what if privateers can't do it, right now the championship is desperate for as many works drivers as possible.

If they are heading back to service, is time really THAT tight so a team mate couldn't wait a few minutes for the driver?

It's OK saying it's not in the rules, but can't see how it could disadvantage the championship in any way whatsoever if they changed the rules to allow.
