This is going OT, but I think Grosjean’s Bahrain crash highlighted how obsolete and dangerous Armco barriers at many F1 tracks have become. That barrier he hit was clearly installed back in 2004 when the track was being built, when F1 cars were considerably smaller and lighter than what Grosjean was driving. At 100+mph, the extra 150KG of mass creates a significant increase in kinetic energy, and it’s clearly gone beyond a critical point where it overwhelms the structural integrity of those barriers if a car hits at a certain angle. A 2000s-spec car might bounce off it and make a dent, a car now might split it wide open - and like Gav says, if it wasn’t for the Halo, Grosjean would’ve met the same kind of fate as Helmuth Koinigg.
Whenever I see unprotected Armco barriers at F1 circuits now, I fear there’s a chance the same kind of accident could happen again.
It’s an issue which seems to have gone too much under the radar so far.
