This season should be interesting, former top teams are off pace and the "diffuser" teams are dominating. Rosberg could win his first race this weekend! He has the speed, just needs to have the race. According to the commentary over here, the cars are faster this year than last by .5 seconds.
Also, I was thinking, when Vettel spun off and stalled the car, what was he doing? He spent a fair amount of time in the car, like he was trying something. If someone stalled their car with KERS on board and fully charged, and it was the type that connected to the front of the crank, couldn't it be used as a starter?
Edit:Wait, I just realized, the commentary here said that it can not be used at speeds under 100kph I think. That would mean no KERS at the very start and when stalled.
