For the last 16 years, drivers and fans have called for one thing every time the Spanish Grand Prix comes around - ditch the chicane and race through the fast right-hand corners at the end of the lap.
Well finally, earlier this year, event organisers announced the return of the two, sweeping right-handers to conclude the 2.894-mile lap around the Circuit de Barcelona-Catalunya.
Gone is the old Turn 14/15 chicane, which was partly introduced for safety reasons and hoped to improve the racing.

However, it appeared to have the opposite effect as the cars would concertina at the apex, only for the driver in front to get on the throttle earlier, which made it hard to be close enough to challenge for an overtake into Turn One.
How much faster is the final sector?
Max Verstappen's pole position time of a 1:12.272 on Saturday was 6.478 seconds quicker than Charles Leclerc's lap in Qualifying from 2022.
In 2006, when the current penultimate corner was previously used before this weekend, Fernando Alonso set a 1:14.648 to take top spot in Qualifying, but the cars were very different back then and Turn 10 was also tighter compared to now.
The big question is if the cars will be flat out through the last two corners, something which has divided opinion.
"Our car has never liked that chicane. I've never liked it," said Lewis Hamilton. "So we're going to come out of Turn 12 and then flat, probably flat-out through the last two. It's going to be great for our neck, great for tyre wear, and it's going to be fun."
Lando Norris added: "It will be even more physical on the neck, so I'm not looking forward to it at all. Whether it's going to make for better racing, I hope so.
"It's a tricky last corner, to be honest. I wouldn't say it's going to be flat-out, but I think it should help with the racing. It might become more of a management race than what it already is, and it's already a huge management race."
Will the 2023 layout improve racing?
The Circuit de Barcelona-Catalunya is not the most difficult track to overtake at on the F1 calendar, but it's certainly not easy.
F1's current generation of car has been made to improve the racing, so the cars can follow more closely. In general, this has been achieved, although there is still a degree of dirty air which makes it hard for the car behind to follow.
It's not a guarantee there will be more overtaking due to the changes, especially if the car behind in a battle is forced to lift more than the driver in front on heavy fuel.
"It's going to be exciting to try the original layout without the chicane. It always seemed like a great sequence of corners - the last two corners - with it being so high-speed," said Haas' Kevin Magnussen.
"Let's see what that does for overtaking. I have a feeling it might be slightly better for overtaking but time will tell."
More tyre wear, more strategy options?
The Circuit de Barcelona-Catalunya has traditionally been one of the highest degradation tracks on the calendar due to the higher speed corners and abrasive surface.
Even before the layout change, the front left gets punished a lot and Leclerc thinks the tyre will be "crying" during the 66 laps on Sunday.
"I think the left front will be crying for the whole race," said Leclerc. "It's the same for everybody, it's going to be a big challenge I think in terms of setup, and also to try and help that left front as much as possible.
"I hope that with the new parts we bring, we will be good in terms of tyre management, because I expect this to be the main thing in Barcelona."
Barcelona is usually a two-stop race anyway, so it's possible three pit stops could be required on Sunday, simply due to the extra stress the tyres will get from another fast corner, rather than a slow-speed chicane.
It's fair to say tyres will be a major talking point this weekend.
