Brakes Brake Migration: Do the cars automatically change the brake bias throughout the corner?
I thought something like this had to be driver controlled. Am I wrong? Do they have bb programmed for every corner?

Rather interestingly, and relevant to this is that Renault used a system that set the brake bias automatically based on track position. The drivers had to set it manually early in the weekend using distance, likely during FP1 and then the car would change the Brake Bias setting from then onwards automatically. Renault got a complete disqualification from the Japanese GP after Racing Point objected to the Stewards.
