Looking at the occasions we’ve had wet weather this season as well as previous, I think the car is more of an important factor than people think If i’m honest, take the Ferrari-McLaren contrast this season in those particular conditions for example.
If I was harassed into giving an answer, I’d say Lewis or Schumi.
I haven’t notably seen Lewis excel in full wet conditions although in mixed conditions I’ve got more of a reliable comprehension: Spa 2010 & 2011 qualifying,China 2010 & Hungary last year as examples. Talent is permanent & looking at the occasions where there’s been full wet weather conditions, it’s either a renowned tactical blunder by McLaren or the car simply not being competitive in those conditions, that hinders Lewis from showcasing whatever excellence he has in the wet, in conclusion, it’s a combination of car [setup] & driver as we saw with McLaren in Canada last year.
