Contrasting views recently from the two world championship protagonists of 2017: Lewis Hamilton said there was no excuse for Formula 1's producing less spectacular racing than Formula 2, while Sebastian Vettel suggested that those unhappy with the lack of overtaking should stop complaining, and accept that some grands prix will always be boring.
It was perhaps Abu Dhabi that prompted Hamilton to say what he did, for while the grand prix was beyond tedious, the two F2 races provided excellent racing, and relatively unsophisticated 'aero' had much to do with it.
I can't take issue with Vettel's contention that 'overtaking should be an achievement, and not handed to you' - of course it should, which is why so many of us loathe DRS, and, like Ross Brawn, wish to see it expunged from F1.
