Cape Town - Unable to follow close given "fundamental issues" with the Formula 1 cars, Lewis Hamilton says something needs to be done to improve the racing.
Last time out in Austin, Hamilton, Kimi Raikkonen and Max Verstappen delivered a grandstand finish.
The trio were separated by four seconds heading into the final 10 laps of the race with the gap dropping to less than two seconds with five to go.
However, even with Verstappen and Hamilton both within DRS zone of the car ahead, neither could make a pass.
"I really enjoyed the race," Hamilton told Autosport.
"Kimi drove great, Max drove great. Seeing that there was three of us, at one point there was me and Kimi wheel-to-wheel, I thought it was awesome.
"I wish it went for longer in that first stint, and the next time it happened.
"And then at the end with us three in that train I wished the race could continue, because it was awesome, and I was hoping we might get to manoeuvre."
The championship leader cited "fundamental issues" behind what is perceived as a general lack of good racing in Formula 1 today and hopes the sport's powers-that-be will focus on that when deciding the 2021 regulations.
"Fundamental issues in F1 are that you can't follow, so there's big gaps between us all," he added.
"I really, really hope that whatever the guys are doing they are making some good decisions for 2021, so there's not a second and a half you need to get close to a car.
"I hope it's a lot less than that. If you get it a lot less then we're gonna have the best racing series ever."
Hamilton would also like to see the gap between first and last became less pronounced in the years to come.
"That's a fundamental issue of the sport," he added. "There shouldn't be such a big difference between first and last, there shouldn't be such a massive difference between cars.
"How can a Williams or a McLaren be three seconds off a lap? That's a huge amount of performance.
"It's got the potential to be the greatest racing series there is, but you look at MotoGP and they are wheel to wheel, fighting from corner to corner."
