I hear you. Everyone makes a mistake at some time, and it's my personal opinion that what goes on in the car, stays in the car.
I have a theory, and it may be a weak one, that when Rod was saying"where was the f**king chicane call?", he wasn't so much asking Sammy as asking himself, like, where was it in his brain and why did he miss it? It's only a theory, mainly because I could hear myself asking myself the same question out loud if in a similar situation.
Regardless, the first question after a hit like that should be "are you ok?".
2. I definately would have got off the brakes and just hit the chicane. Hitting a chicane isn't the end of the world, flat spotting all four tyres and going hard into the scenery is. Check out the skid marks in Sav's video at 3:34!
