In answer to the OP, that 1 finger salute along with the way he screams “yes, yes, yes, that’s what I’m talking about!” repeatedly when he wins is what makes him terrible for me.
With regard to the dominance of Vettel/Red Bull, that doesn’t bother me as much as all the other nonsense around conserving fuel, mincing around on tyres that will only last a few laps, drivers not being able to overtake on track because there will be a ‘better’ opportunity when they come into the pits to leap frog the person they are trying to overtake.
And a lot of the tracks don’t help. Places like Monaco are impossible to overtake on, even though they are supposed to be the highlight of the calendar and then you have other places with tons of run-off (smooth tarmac, not gravel) so there is little consequence to a driver’s actions. Obviously the racing should be safe as possible, but some of the drivers try stupid manoeuvres safe in the knowledge that if they don’t work, there is hundreds of feet of tarmac to use and get back on the track, rather than 6″ deep gravel that they will get stranded in.
Oh, and safety cars……people work really hard to build up a gap and then the safety car comes out and bunches them all back up so any strategy goes out of the window. They all have GPS, so why not have a system where they can still circulate the track but are held in position, give or take a certain amount of allow for all that tyre heating shenanigans….
