Having KERS fully-charged from the start, so it can be used immediately after the lights go out...
This suggestion was made today on Facebook by David Blundell (thanks David!). After reading it I realised it's probably the single most simple and effective protection against being held up behind a car on the opening two laps which has cold tyres or an absent manager. It's also how it works in reality, as drivers use their KERS off the start line. We were attempting to tweak the overtaking code as a solution, but actually I prefer this idea and think the overtaking code could stay virtually unchanged.
But we want to hear some more opinions before we go ahead and do anything about it. So, what do you think of this idea?
