My opinion is the same as many opinions posted here. Maldonado's incident in this race wasn't intentional. It was 100% his fault, but he didn't mean to hit Perez.
What worries me is that this obviously isn't the first time, or the second, or even the third time that he's been involved in this sort of incident. And he still keeps being a bit too aggressive. Even though most of his clashes weren't intentional, they were his fault and he could use some harder penalties than just the odd fine or a 10-place grid penalty, because it's not like these penalties got him to change his mind yet.
