Cool McLarens

[Viktory]

In qualifying (the last part) both for this and last race (don't remember if they did in Aus), one or both McLarens have lined up way before the green light is about to come on. They have been in very warm climates too. Isn't it a little risky? I guess they have pretty good understanding of what the engines can take, but isn't it pushing their luck a bit? Interesting to see some smoke from Hamilton's car in Quali also.
What do they gain from doing this? luring out the others maybe, to put more pressure on their engines.

Gives them 1st crack at a clean lap after burning off fuel !
