If I was Hamilton I'd try and beat him, but if it looks like he's not gonna get passed with a few laps to to. Sling one up the inside and let rosberg decide if they both finish or not.
Try and scare him down the escape road at Mirabeau....... If they both end up in the barrier, Hamilton still has title lead, if rosberg bottles out of it, Hamilton wins.
If rosberg goes down the slip road, dependant on how close the red bulls are, he could end up 4th as he waits to back out again.
According to sky. Within a few months. The teams will have the engine so efficient that they wont even have to carry the maximum allowed fuel to get through the race.
Its not a bullshit rule site, they have to limit something to stop costs spiralling. They could have limited turbo size, maximum boost allowance(as the btcc do) and many other things. But they havent. You can have as big a turbo as you want. As much boost as you want.
You just have to make it efficient to run. Something that is more relevent to road cars.
