Ferrari's cheating engine last year forced Mercedes to work harder to stay ahead. They did, and Mercedes were suddenly left miles ahead of Ferrari and everyone else when the FIA did what they did.
Mercedes aren't just winning because they're outspending the rest, they are truly the best team on the grid. They have the best driver and team galvaniser in Lewis Hamilton and the winning mentality. Even in today's interview, Toto Wolff is still saying "we don't think we've won the championship. We take every race as it comes and try to win the race, rather than focusing on the bigger picture." That's the same mentality that Liverpool have used to great effect in the Premier League - taking it one game at a time. Ferrari are a championship focused team which is why they keep bottling it.
Mercedes dominance is all on merit. This is nothing like the Ferrari dominance at all. That was a company bullying the FIA to make the rules so they could win, partnering with Bridgestone to make tyres that only suited them, and a team that spent their entire time pounding around their private test track with a star driver and a contracted whipping boy.
Mercedes are using spec tyres, fighting against Ferrari's veto, can't test anywhere and have always had two drivers allowed to fight that only use team orders when absolutely necessary, and are always embarrassed about having to do it.
Mercedes got the car design philosophy correct - long wheelbase and low rake - at the start and keep developing it. Stable regulations should converge at the end - which the midfield are doing - and this is exceptional engineering from Mercedes to keep ahead.
If you don't like it, we could always go back to there being too much COVID around and F1 not racing. The choice is simple - Mercedes dominance or no F1. Choose. Be thankful it's back and at least enjoy the fact that this car is breaking lap records again and again. The onboards of the W11 are extraordinary and its a glory to watch. It's quick and its driveable, enjoy the lap times while they last. It's not ideal and a Barcelona 2016 moment wouldn't be met with much derision, but you've just got to accept its happening and try to find something to enjoy about it, because there is plenty else this season that is spectacular.
