Max hates understeer as it's slower, so he sacrifices rear end stability for front end grip on turn in, and somehow can manage the rear end instability that other drivers can't

There's more of an explanation from one of his online team mates here

"At the beginning of the season, the Red Bull was lazy, and was easy to drive because of the understeer.

"Understeer is very a boring way to drive a car because, whatever you do with the brake pedal, at a certain point, the car just does not rotate anymore.

"What Max does very well is a balance a car that is too pointy, no-one else can handle it because they start sliding and he manages to make it perfectly smooth and uses that extra rotation and he can cancel that when he doesn't need it."
