The new-for-2022 regulations were established specifically to improve the spectacle and increase overtaking by reducing the turbulent wake of the cars, with an emphasis on generating downforce from the floor.
But while the gaps between teams have closed up since last year, producing one of the most competitive midfields in recent history, the on-track spectacle remains a point of concern.
A distinctly lacklustre Azerbaijan Grand Prix brought the topic of how well this crop of cars races back into the limelight. After a race in which it proved almost impossible to pass despite the long straights, several drivers questioned why Baku's main straight DRS zone was shortened.
Red Bull duo Verstappen and Perez proved the exception as their RB19's extremely efficient DRS device and superior top speed allowed them to breeze past Charles Leclerc's Ferrari.
But even they acknowledged that overtaking has become more difficult compared to last year due to the extra downforce the teams have added to the cars. And they warn the situation will only get worse if the current rules are maintained.
"I feel this year [overtaking] certainly has become a little bit harder," Perez said. "These cars are generating a bit more downforce and by generating that little bit more downforce, the car behind struggles a little bit more to follow.
"So, in my opinion, it wasn’t the right thing to shorten up the DRS, because it's already harder to overtake than last year. So it's something we should review."
