The 107% rule is stupid! There aren't 26 teams in F1, there are 12!
What I mean is, there isn't the problem of housing all of the team in the pits, so I see NO reason why this rule was implemented.
To try and ensure that the drivers/teams competing meet some sort of performance standard. I don't have a problem with it existing on those grounds. Far more annoying is the fact of Prodrive, for example, not having been allowed in while HRT (no disrepect to the team) was.
