Is Verstappen faster when angry? 'Then the lion comes out'

Max Verstappen was angry after a poor qualifying session at the Brazilian Grand Prix. He felt the race organisers and stewards had not handled the red flag properly when gridmate Lance Stroll crashed. A few hours later, Verstappen drove an incredible race, moving up 16 places on the grid. Is Verstappen a better driver when he's angry? Giedo van der Garde thinks he is.
