I know it has been brought up before, but I will bring it up again. The guy with the most victories should get the title (when all of their other finishes are similar).
In other words more points should be awarded for a win. I feel the gap should be 4 points for a win to second place. If they would have left the scoring gaps alone and simply extended the points down to 8th, we would not be having any conversation as Massa would have clearly won (the title).
Essentially, yes, I agree - there should be a bigger gap for 1st (and maybe 2nd), like there was when points were only awarded for the first 6 placings. The system we have now doesn't incentivise a driver to push for a win, as the difference in points isn't worth the risk of potentially running off the road.
However, we probably would still be having a conversation about the year just gone, as Massa got a victory in Spa that was taken away from Hamilton (not going into the rights and wrongs, just the facts) and that obviously changed the 'win count' for both of them. Also, if the scoring had been different, would either driver have pushed harder - and not settled for a lower place - at some races in the season? I'm thinking of Hamilton finishing third at Singapore, where if there were a larger points gap, perhaps he would've attacked Rosberg harder.
My point is that retrospectively discussing how the season would've gone if the points allocation were different isn't really going to get anyone anywhere. I'm sure that several placings could be swapped round if points were awarded for fastest lap, pole, leading a race lap etc. etc.
What they should have done is offered 100 liters of fuel for the race distance and completely opened the engine formula (if green was the real name of the game) The following season, 90 liters of fuel, etc.
That is a good idea. I believe it's what they're doing in the MotoGP racing. The only odd result of it is that the bikes apparently have a system that manages power according to fuel use. Occasionally it results in a bike having a big drop in power for the last couple of laps, which does makes results interesting, but probably isn't much fun for the rider!
