Formula 1 drivers are already pushing for changes to be made to the Madring circuit after its debut Spanish Grand Prix produced a lifeless dud.
Madrid's new F1 race was low on drama, with its newly-built street circuit providing little to no overtaking opportunities in Sunday's race.
Drivers had anticipated a chaotic weekend on a track called a "car killer" by four-time champion Max Verstappen.
Potential changes were already raised during the regular drivers' briefing on Friday, held after the first two hours of track action in practice.
Reigning world champion Lando Norris said it should have been obvious the circuit was not up to F1 standard.
"I think there are some obvious changes they should make," Norris said on Sunday evening. "They should get rid of [Turns] 18, 19. Useless. Just have more of a straight into a hairpin. Like, I don't know how someone looks at this design and goes, 'mint.'"
Race winner Kimi Antonelli said: "It definitely doesn't create overtaking opportunities and it doesn't push you to try and make a move because 80% of the time you might have a contact."
Madrid's circuit, which has a 10-year hosting contract with Formula 1, is officially a street circuit but much of it is built around an empty exhibition centre.
Haas driver Oliver Bearman echoed Norris' view, saying he and his fellow drivers had been deflated by what they saw when they arrived given that the designers effectively had a clean slate with what to make.
"It doesn't take a genius to make a track layout that lends itself to overtaking," Bearman said. "They managed to do it in Baku and Baku had a lot more limitations with buildings around it. On that sense, it's been a bit of a disappointment, but hopefully next year it will be a bit more interesting.
"When you arrive and you see that layout and you are like, 'what do you expect us to do,' it's a bit disappointing ... Basically from Turn 5, all the way from 17, there was a bit of free rein, let's say. I don't think that free rein was used to the best of its potential."

Norris thinks the circuit can still be salvaged into something much better.
"I think there's a lot of opportunity," he said. "I think they can make it into a track that's good for racing, and I'm excited to come back here next year if they can make these changes because I think it's a track that is good fun to drive and it can be a great racetrack. To me, it's not a great racetrack.
"It's great in qualifying, but, you know, straight line from 17 straight to 20, [it should] have a much wider entry like Austin Turn 1 or Turn 10 in Austin, [a] big hairpin.
"You know, you'll create much better opportunities for everyone and you'll be able to enjoy the race. So yeah, there are some simple changes and maybe some trickier ones, like Turn 5, 6, 7. It's hard to know exactly what's the best thing. The fact you have to turn and brake basically defeats the whole object of racing.
"So, they can do some simple changes, I think, easy changes and maybe some more tricky, but I hope they do it because then it should be more exciting for everyone."
Ferrari boss Fred Vasseur said the organisers deserved credit for the event as a whole, even if the race product was lacking.
"I have to say that we can discuss about overtaking, but overall for me the event was mega, the infrastructure, that we were mega welcome in the city, I think we have also to be fair with them and to congratulate Madrid for the job done on this side," he said.
"Now they came to us on Thursday [and again] on Friday evening to see if we think that it will be difficult to overtake, and they are keen to do modifications in the future, they have probably more latitude in Madrid than in Monaco to change something and let's work together to see if we can do something.
"Overall I think we have to be fair with them, it was a good event."
