@PM, Why, he caused a crash which delayed the recipient.
And Webber, crashing out, by his own admission was his own fault. He said he was trying to get back to the pits asap, and the crash was the result of going too quickly.
He was driving too fast with a damaged car. He would not have crashed out with a car in pristine condition. The damage was damage was a direct result of contact with Massa. Ergo, no penalty was necessary.
Even if Webber made it back to the pits, I still doubt he would have been penalised. Massa turned around, and while he was disadvantaged, Webber needed to make an unscheduled pit stop to replace his front wing. He would have had a bigger disadvantage than Massa. Again, no penalty is necessary. Penalties should only be issued when one driver clearly disadvantages another.
One thing I’m confused by: Liuzzi had a 5 place penalty, but he was 24th anyway.
Would it not be better if he started on the 29th grid slot on the straight?
How is that in any way a penalty? If anything, it’s an advantage – he would be starting on the clean side of the circuit, with five empty grid spaces before him. That would give him more time to pick his line into the first corner because he would be able to see what the other drivers are doing.
