Vettel is winning so resolutely because he has the best "package" on the grid. He's got one of the best, if not the best, F1 cars of all time*, he's got a well funded team, he's got great skill and he puts an immense amount of effort into it. I don't see how anybody can claim he's not deserving of his success.
Of course, if Newey was still at McLaren then Hamilton might be on his 4th WDC by now, Redbull could be midfield at best - as Jaguar they didn't set the world on fire. Or if Newey had been offered a share of Williams when he asked, he might have got Rosberg a bunch of titles there instead.
But whilst the car is responsible for a massive degree of success, Webber shows that skill is still critical. It's insane to think that RB would purposefully sabotage Webber's car though - you can never have enough constructors points.
There are occasions (such as the front wing last season) where Vettel gets one-off components if they've not built enough by race day, but there's nothing wrong with putting your effort/money where you'll get the best return. I think Webber just doesn't handle the car as well as Vettel. Listen to his engine note as he's going through corners - often more stampy that Vettel, often less clean lines and iffy kerb hookups. Plus if you can run in free air in P1 for 2 hours (which you get by qualifying best and not f**king up) then you're going to stress a marginally healthy car less. If Webber didn't want to overheat yesterday he should have qualified better and got in front of Vettel to enjoy the breeze!
After all of that, I'm not a huge Vettel or Red Bull fan, but I am a motorsports fan. The guy is thrashing everybody and deserves acknowledgement for that.
Did you see how fast he opened the gaps when he needed to? Dude is driving multi-seconds per lap faster than everybody else. That is impressive.
Alonso is another hugely impressive driver, and I suspect he's noticeably quicker than Vettel but unless they end up in the same chassis we're unlikely to ever know. He reportedly does the same simulator hours, the same debrief, the same attention to detail that Vettel does and I think this is contributes to his quickness. It's a bit of a shame that Kimi can't be arsed with the off-track work because I think he could be fastest of them all if he did, but if he can race for top F1 teams, win titles and do it all in a few hours every weekend then nobody can complain
Roll on next year - the regulation changes should be a reset. Mercedes power should be superb because it's almost impossible for them to f**k it up because Mercedes, Renault power is probably a little less impressive, but RB are almost certainly going to have an aero advantage except they're going to spontaneously combust a few times in the first third, giving Mercedes time to bank some points whilst the non-AMG engines wail about power parity.
And whilst that's going on McLaren will come back with an awesome 2014 car and win WDC with Jenson
Just don't f**k up the front aero!
