I assume Bottas was attempting to lay some rubber down and over cooked it.
Fully agree with
Brogan that Perez will win the WCC for RBR however, it's interesting to note that Hamilton spoke up massively for Bottas in a recent interview regarding Hamilton's contract negotiations.
As I said a while ago, Hamilton is Bottas's best friend at the moment because Hamilton would obviously prefer a teammate he has the measure of rather than someone like Russell who may not be so easy to beat.
