The Chaos in the End of Formula One

I wonder how far Formula One will go until it's like no this is too much the question I was going to ask is why was there so much chaos in the end of that race. It seemed like everybody had no grip it was almost like it'd been raining or something it was mad. Even though most cars were on soft tyres which was actually a good thing because it would have been even worse if we were not. The lap that we did the warmer lap it was really slow because there was a safety guy in front so we couldn't really warm up the tyres and it's a track where you know people were struggling to to warm them up already in quality.
