I am not sure how did you managed JT include in RBR' mistake, but whatever. How often RBR released a driver with incorrectly attached wheel - compare it with McLaren? I hope that you know that under JT' leadership he is slowing cars down. For example next year pit lane speed will go down, etc. Check the facts, just as I am not sure you can hang Pirellis on his neck.
The WMSC recently mandated head protection for pit crew. If nothing else this incident points up the obvious, that head protection should be worn by everyone or no-one who works in the inner lane of the pits; cameramen, TV reporters, VIPs etc have skulls just as fragile as mechanics. You can't go onto any building site in the UK without a hard hat, whether you're working or not. The risk of being hit by something in an F1 pit lane is arguably greater.
My point about Todt is that he doesn't want to upset anyone. He will allow things to go through if other people want or suggest them - e.g. the mechanics lobbied the teams for a reduction in the pitlane after some of their colleagues in other categories got injured, the teams proposed it, Todt was happy to do it. That's fine. What Todt doesn't do is push things through that the teams might not ask for or want, like stronger tyres for exampe (and I don't blame Todt completely for that because Pirelli were not helping matters by denying there was a safety issue, but Todt allowed them to get away with it). It's Todt's job to drive forward improvements to F1 safety, and to react positively and proactively and decisively when there are problems. I'm not satisfied that he does that.
