I’m just guessing here, but when Häkkinen became a father, he said he lost his fearlessness that you need to compete at the top level. I know Checo already has children, but he has just had a fourth one, so maybe his mind his there a bit more? Combine that with Verstappens hyper domination that would easily crush all but the toughest minds. I have no idea whether he actually believed that he could challenge for the WDC after the first four races, so that might play a part, too? He has always had mid season slumps at Red Bull, but this one is turning out to be quite a big one…
