I will agree about the SIM racing. It's what he does to relax. Nico Rosberg complained about him playing SIM racing as well. Max and Lando are a different generation, to them it's normal whereas the older generations don't understand it.
Max was taking part in a 24 hour race with his team so was up late and up early to do his stints in the SIM racing. So I think that affected him on track in the GP? Nah not at all.
It's all been blown out of proportion, it's not like he's gone skiing or rock climbing or playing football before a race.
Btw
@ArjenIsM3, do you think RedBull have made a huge mistake going away from last year's all conquering car concept? I find it incredible that a 20-30 second lead (that max had in most races last season) has been turned around so quickly. I think this is one of the reasons he's so angry.
