Max Verstappen has branded the new pit-lane rule in qualifying as "absolutely terrible" after its implementation at the Sao Paulo Grand Prix.
A new minimum lap-time delta was introduced earlier this season to ensure drivers weren't going unnecessarily slowly on out-laps in qualifying and impeding others.
However, drivers figured out a way to "game" the system by backing up the pit-lane exit, with Verstappen among those pinged for the breach in both Singapore and Mexico.
To combat it, race director Niels Wittich introduced a new rule ahead of the Sao Paulo weekend whereby stopping in the pit-lane itself was forbidden, but if drivers moved to the extreme left of the long pit-exit, others could pass on the right.
George Russell, Esteban Ocon and Pierre Gasly were all hit with two-place grid drops ahead of the race for impeding and ignoring the rule - of which Verstappen has hit out.

Verstappen not a fan of new rule
"Absolutely terrible," Verstappen began when asked by media including RacingNews365 for his thoughts on the rule introduced by Wittich.
"On this track, you have quite a long pit-exit and there are some walls, but on other tracks, if we implement this, you will be driving very slowly on to a straight where people are passing at 300kph plus.
"You are maybe driving at 15/20kph to make a gap, which I think is extremely dangerous.
"For me, it doesn't work at all, it just creates even more trouble.
"Look at what was happening [in qualifying], with people going on the grass, including myself to try and pass cars.
"It is just a mess, every single qualifying you have six to eight cars getting noted for driving too slow with the minimum time. I don't know what we're trying to achieve."
