Yes, I think the bigger part of the guilt is on Max, but RIC's 1st move was to the outside and then very fast to the inside.
It depends a bit on what Max reacted to, did he go inside after seeing Daniel went outside to have the defensive/inside line or did Max go inside after Daniel for a blocking maneuver?!
Not trying to justify, I just see 2 scenarios I can't judge if it was one or the other.
I agree, Riccardo moved so fast to change line and everything happened really fast. I believe it's a racing incident.
