Meeke and Tanak took the wrong way, the rest they didn't say.

They showed it on alllive.

Ogier now saying Mikkelsen also maybe went right, but he isn't sure.

yes those valves, maybe flaps is better to say about them? google translate wasnt very helpful about this those didnt open according Lindström, yesterday the had the problem that it didnt close before the watersplash

And Latvala's went wonky today too which caused a misfire. Sounds like the last part id have imagined failing.

The wall thickness is super thin... and the gusset is also silly thin...Anything for weight I guess but there are rules.

There are clearly given requirements for the rollcage and during the homologation the manufacturer is obliged to proof they are met.

I admit I don't know what exactly is required now but when I studied the rules roughly ten years a go the rollcage was being loaded only in a semi-static case in the homologation testing/simulations per FIA requirement (15 seconds to reach the full load if I remember correctly). The testing load was 7,5 x (vehicle weight + 150 kg) for the main arc and 3,5 x (vehicle weight + 150 kg) for the front arc in that time (no crack and no deformation over 50-100 mm as a limit was required). The minimal size of the broken tube was 35 x 1,5 mm if I am not mistaken. It's very clear that in this case of Bulacia's accident the load compared to the testing conditions was higher by an order of magnitude at least.

It looks horrible for sure but we don't know how other rollcages would behave in the same kind of accident when the car flies in the air and lands exactly on the roof. This is very freak accident configuration.

Having assessed the damage back in service, the team have decided to retire @ElfynEvans and will now focus on preparing the EcoBoost-powered Ford Fiesta WRC ahead of the next event in Chile #WRCLive https://t.co/DyiEQmtjHD
