In my experience on events like this, you will always have a few clueless drivers who forget everything they know and drive like idiots. Group mentality, not least amongst slow traffic when you are trying to keep up. I've seen many crazy moves that I would not do, I am of an age where my risk appetite reduces by the day. Added complexity when driving abroad as you have a bigger blind spot due to the side you sit.
No sure why the Ferrari wanted to keep going here, right thing to do was pull in behind the Lambo and follow them around but he just kept going, silly move. Yea the Lambo should have accounted for that but seems blind spot was at play and also they he would expect the Ferrai to continue to follow. Rented Ferrari so suspect the driver was suffering a bit of red mist.
