World Champion Lewis Hamilton says Formula 1's aim of lowering lap times from 2017 won't have the desired effect of increasing the on-track spectacle.
Formula 1 chiefs are keen to introduce regulations which will see the 2017 cars around three to five seconds faster than their predecessors, ostensibly through increased downforce levels, but Hamilton is unconvinced that such a change will help.
Hamilton's comments come a week after the Grand Prix Drivers' Association penned an open letter, criticising the rule making within the sport.
"There's been a lot of talk about the rules and whether the drivers should be more involved in decision making," he said.
"It's not our job to come up with ideas and we all have different opinions anyway.
"But personally, I think we need more mechanical grip and less aero wake coming off the back of the cars so we can get close and overtake.
"Give us five seconds' worth of lap time from aero and nothing will change - we'll just be driving faster. I speak as somebody who loves this sport and loves racing.
"I don't have all the answers - but I know that the changes we're making won't deliver better racing."
