I was wondering about that yesterday, but I'm not close enough to current F1 to really have an opinion. I accepted that warm and dry alternating with brief-but-heavy downpours is usually the domain of the inter - rarely the optimum tyre to be on, but more forgiving of bad/unfortunate decisions.

That said - the current F1 inters seem able to cope with a lot of surface water.

That is a good point. Do they keep them in storage between seasons or will they just be scrapped?

They recycle all the tyres after a race weekend.
The full wets are notoriously bad but the other thing is the spray is so bad that the race will get red flagged/safety car brought out.
Always thought they can just get rid of the wets and save some of those emissions they keep bleating on about.

Only the slicks (according to this guy)

It’s been like that for a few years, can’t remember the last time they ran for any length of time on the actual wets.

I’m not saying the safety car was the wrong call, but like you say, if they’re not going to be allowed to race when it’s wet enough for actual wets then what’s the point having them?

Exactly. I'm not really commenting on whether they could race in wetter conditions given the tyres (looking at the Hadjar crash, clearly they were close to the limit of safety given the spray). I just don't see the point in even making that wet tyre.

They might be better to make that inter be called the full wet, and make an inter tyre that's slightly shitter in the wet but better as it dries.

I wonder if there's anything they can do with the tread design to make the spray better? Eg. Send more water out further sideways or upwards or something. Dunno, there's some clever people out there.

Most of the work on reducing spray seems to centre around sticking guards behind the wheels.

Current cars being so big and using the floor for so much of their downforce seem to make it worse than in the old days when you got a pretty narrow but really tall rooster tail. Now it just seems to be a solid cone of spray comping out from behind the car.

Yes the amount of water lifted into the air along the national pit straight from our seating position was absolutely incredible - like a thick 50 foot high dense fog. I can't imagine how you can see anything in the middle of that

Yeah this. Ruins the race imo. Get them on full wets and carry on. I ended up FFwding through most of the first 25 laps.

I’ve seen on TV features that they do all the tyres, the reason being that once they’re put in a blanket and warmed up the rubber begins to cure and get harder so you can only do it so many times before the tyre property changes

<shrugs> Start of that vid highlights that Pirelli go through >1200 tyres per race. And OK they get recycled rather than burned, but that. Is. A. Lot.

Wonder how much rubber is worn off over a weekend? I bet they don’t sweep up and recycle the dust and marbles strewn around the race track.

Literally it’s only use is running behind the safety car in an attempt to clear some water from the track, but it creates so much spray it’s too dangerous to do

Can’t say for other venues but Silverstone run the sweepers around after every race and once everyone is off track after the final f1 race. There’s still so much rubber in the gravel tracks though, and if you’re lucky you can find little pieces of crashed car the Marshals miss. I’ve got a little piece of Felipe Massa Ferrari from one of his sillier moments when he crashed solo in practice at the pit entry after loosing it at Stowe

How small is a little piece?

We left promptly after the race yesterday but now I wished I'd gone carbon fibre hunting

I have a silly collection of tyre marbles from various motorsports events

Jolyon Palmer analysis of Piastri penalty. Some good data-based insights.

The brake pressure difference Oscar to Max is fairly damning imho, the stewards were fooled or just fools.

Couldn’t risk the current world champ getting a ban.

I've flip-flopped on this one :
- watching it live I thought Piastri did nothing wrong.
- reading the stewards report regarding his brake pressure and rapid reduction in speed from 120-odd to 20-odd mph - I thought maybe the Stewards were right after all? Although for me it was clear that Max wasn't anywhere near the limit of braking as he sailed past, so the idea that he had to take evasive action and was unable to avoid coming past was visibly flawed.
- with further data I am fully aligned with Jolyon's analysis. The data shows that Piastri's braking and deceleration was entirely consistent with earlier actions performed behind the safety car along Hangar and other straights, and entirely consistent with that of other drivers (such as Max). Arguably therefore entirely predictable. You can't claim that his actions were inappropriate/dangerous just because the safety car lights went out and it's now his responsibility to control the race pace.

At the end of the day it's kind of immaterial - his team still got a 1-2, just in the other order. With this data however, they should at least recognise that the decision was made too quickly following an a review of very limited data, and remove the penalty points applied to his licence.
