Do we need sensors or could it be done by the existing circuit cameras + use of AI... or at least the AI triggers a manual review?

Loss of DRS for x laps feels like a better penalty and keeps the racing going.

But then it wouldn't apply in the wet as there is no DRS.

If they do it with artificial intelligence every man and his dog will appeal it.

A good old magnetic strip, no appeals.

It would barely cost anything to implement.
AI is there to scan an image and flag it to a human for inspection, not to make the decision.

Sensor strip would have to be pretty tough to stand up to an F1 car running over it (braking / lateral load etc).

But I like the spirit of your idea.

To me it is simple. The white line denotes the edge of the track, all 4 wheels over the line anywhere on the circuit is 'Exceeding track limits'. Three warnings then penalties as now. No point in marking out the circuit if it is not policed.

Ultimate sanction.

Automated sensors. 3 warnings, then the system plays this at high volume, on a loop, into the earpiece for an entire lap.

This thread seems close enough for this. Track limits, forcing another driver off the track, I'm pretty sure there's contact too. Massa and Kubica in Japan 2007... https://twitter.com/ahmed_baokbah/status/167565080...

The 2023 stewards would throw the book at them hehe

No need to complicate it. Narrower kerbs with a few feet of low-grip surface on the other side and it becomes self- enforcing. That's got to be preferable to any sort of post hoc system, which can only ever be arbitrary.

If MotoGP doesn't like that (part of the reason we don't have gravel), they can lay down something over the top of the low grip surface.

Or the drivers could just stay on the track...

UK track limits rules are far stricter. Perhaps they should implement those and then we'll really see who the best drivers are.

All these technical solutions sound simple but in reality they are from that.

It's funny how the drivers manage to avoid those kerbs when they are wet and don't offer so much extra laptime.......

Is there a thread for this?


Mechanism :

Track =============================
Sensor Strip running 50cm outside -----------

Using the gridbox sensor in-car (nosecone?) if a car 'pings' the track sensor it's a strike.
They have this already, much like other things they are starting to police it, monitoring is now the issue.

Combine it with a ‘Hawkeye’ (goal line tech, cricket, tennis) high speed cameras, with the correct software, automated race control, in/out instantly.

Leave the stewards to steward..otherwise we will end up with a driver rep per team in there.

Nb need to encourage wheel to wheel racing..

Like the punishments thumbup we can add a ERS non deployment as well.

Edit, see what happens when get get rid of AWS, they would have just forecast this for us.

yes I think making it inherently slower to go off-track would be a better approach than making it faster to go off track but penalising drivers for it. I can see the need for tarmac runoffs for safety, but that doesn't mean they need to run all the way to the track - a couple of meters of grass or gravel just outside the track limits, then tarmac outside that, would work.

Or gravel like they used to have. Fine exceed track limits but you will be putting a wheel in a load of gravel. Then watch how quickly they manage to keep within track limits.

That ^.

One of the F1 circuits has done it, I think it is Zandervoort. They have put a strip of that resin boned pea gravel beyond the curbs. Has no grip at all, but equally you can't drag anything back on to circuit either.

This is my solution, equally suitable for cars and bikes

Agreed

Making it not worth going off line is the only way.

I did a day at Porsche Silverstone a few weeks back, they have a circuit made of low friction tarmac, bone dry and hot 26c day and was like driving on soap. Should be more than enough to dissuade.

Yes, you want a surface past the kerb that’s not as sticky as the track, such that you need to lift and it’s not faster to be out there.

Circuits that also host bike racing don’t like gravel on fast corners, but it shouldn’t be too difficult to either find a compromise material, or a solution that can be quickly and cheaply changed between events.

I actually agree with the monitoring, so long as it’s consistent and everywhere. Drivers will quickly learn if the penalties keep coming, in the same way they learn to avoid the white lines when they’re wet, or avoid walls and Armco barriers. Apparently there was a remote team of FIA observers watching cameras last weekend, cameras that had been specifically placed to pick up violations of track limits, so there were more offences reported than usual and the race director’s team on the ground were overwhelmed.

They definitely need to fix the speed issue though, we all want to see offences dealt with quickly and fed back to the competitors, not hours after the race has finished and only in response to a team protesting the result. Perhaps they need more remote observers, or more co-ordination between the remote team and the observers at the circuit? It’s not difficult to imagine a situation where an assistant RD receives one report of a car leaving the track from the observer at the corner, and a few moments later receiving the same report from the remote team, and needing to work out if that’s one offence or two. When there’s a couple of cars a lap getting pinged, and only a 70” lap, it gets very busy very quickly!

How this all works next weekend at Silverstone, where there’s a lot more fast corners with Tarmac run-off, is anyone’s guess!

What about grass and gravel beyond that if it's a fast (dangerous) corner?
