2) You are allowed to change tyres during red flag but it does not count as your 1 mandatory tyre change. So you still need to do another pit stop if you have not done it before the red flag

Still not perfect but might make it less random

I like 2, as it effectively stops the red flag from being turned into a free mandatory tyre stop.

by no means was it a certainty (none of us can see the future) but we have seen before drivers urging on action by race control through their radio messages (so and so went over the line or in this case there is too much water on the track) and when you combine that with most everyone running long on the inters as the first pit stop window was open and with conditions seemingly getting worse...

imo its a fairly a short step from there to everyone was anticipating a S/C or red flag (there had already been like 4 or 5 during quali that morning) and clearly thinking about getting in a free or cheap stop in, and/or how that might actually lead to the race being stopped at the half way mark...

of course this doesnt amount to it being a certainty, nothing can, but watching the race live a stoppage very much looked like the inevitable outcome in those moments imo.

i further question Mclaren pitting at the same time as GR when the overcut option looked to be a better hedge against the very real possibility of an imminent S/C red flag call...i would think that this is why the pitwall dismissed Norris' earlier suggestion to go for an undercut because they knew waiting a few laps made sense given the probabilities at play...but then they just decided to cover. perhaps nerves at that point?

hindsight of course and we will never know what any of the teams' data centres/race simulation teams were predicating at that moment?

Or alternatively add 20 seconds to their race time at the time of the stopage and have them start in the position this would have put them if they chose to change tyres under the red flag.

races that start on inters or wets or a red flag restart requiring inters or wets negates the two compound rule no? rules changes would lead to more rule changes and will only lead to more unintended consequences imo.

such as, its hard to imagine any scenario in todays day and age where FOM/FIA/race control is going to accept the (legal and moral) risk of drivers going out on old cold tires because they know the potential consequences of that...a free tire change is the lesser of two evils really...plus its the sensible and simplest thing to do right?

Let them put warmers on the existing tires if there are concerns about cold tires. Nothing stops a team today from putting on scrubbed or used tires if they are low on their allocation. Teams regularly allow drivers to continue on track with battle damage.

Nobody is making teams use old tires. I think most of these suggestions allow teams to change tires "if they want or need to do so". But with some type of penalty that would be ideally equivalent to the impact of a pitstop.

Absolutely spot on. It was extremely clear that unlike the lottery numbers, this was fast becoming a statistical probability. All of the data was pointing towards a stoppage -

- multiple red flags that morning, and in the support series
- extremely heavy rain at the time
- worn old tyres
- multiple rookies on circuit
- wet tyres not really being much use
- F1 loves to try and avoid heavy heavy rain running

This wasn't predicting a one in a million event, nor does it take hindsight to work out that a red flag was extremely likely. Additionally, with nobody of significance having completed their stops at that point, there was no strategical advantage to George and Lando pitting. If they had stayed out and there was no red then they lose no real time as nobody had pitted. If there was a red then they lose track position.

This is, once again, F1 engineers not looking out the window and working purely from a spreadsheet of data. Data says it would be the optimum point to change to new inters at that point, so they do it. Completely ignores what's happening on track.

Whilst we're on this topic, I was lucky enough to have travelled around with the British GT paddock for the majority of 2025, and spend a lot of time with engineers in the garages. At Donington the weather was 'changable' to say the least. There was a lot of engineers looking at radars and data trying to work out what was going on. I was standing at the back of the garage, with a view out the back door - I could see the sky over the Melbourne Hairpin from my position. It was clearly pouring down less than half a km from the circuit, and approaching. Meanwhile the engineers are buried in the spreadsheet trying to work out what tyres to choose. A Optimum McLaren mechanic was standing with me and we were gesturing to look at the sky - it was clear what was about to happen. An engineer eventually did and made the call to switch. Sure enough, massive downpour, many cars off, because they made the call a lap late. But it was obvious to anyone not looking at a graph.

That's how I feel George and Landos decisions were made. Nobody was watching the race and everyone was buried in data.

Both of these. Sometimes leaning back from the screens and the old hand out the window technique is most accurate. But I want 90% of the data from the cars back to the paddock cut. Let the driver feel the car. Yes I get it they're very very advanced and that will have its own issues but are they any worse than things now can be at their worst? And the sheer amount of carbon needed to run all that kit would easily persuade every boardroom it's a "positive thing" for marketing guys to use
