If Mercedes delivered the goods in Spa, Monza, Turkey, and Hungary, they would be leading the championship right now. It's been fairly 50/50. Merc had their tracks. RB had their tracks. What you are seeing is the fact that when RB is quick, they convert to wins. When Mercedes are quick, they do not convert to wins at the same rate. Merc have had their opportunities, and they wasted most of them. In the end, I'm quite content with what we've seen. The difference has simply been Mercedes unable to deliver the goods when the tracks favored them. Instead, taking engine penalties, running poor strategy, and a driver error here and there.
Anyone thinking RB are dominant is just looking for excuses to absolve Mercedes of any blame for losing.
I haven't seen many saying that Red Bull is dominant.
