copy pasting my reply to the other guy because it answers you;
Vettel had to brake later and accelerate earlier, all while using less track to do it, since he passed on the inside.
He did do that yes.
This takes massive balls considering they are already on the edge of speed + grip + and cornering ability.
No. “they” were not, bottas was, vettel was not. Vettel had fresh tires, bottas had well worn tires. There’s a huge difference in cornering and braking ability between the two.
Bottas could have possibly defended it but was probably focused on staying on his racing line and did not react in time to block the inside lane, or he didn’t have the balls to brake that late and go that far inside the corner.
He was already defending, WAY inside from the racing line. If a car can pass him from this position, the car is getting around him period. if he went further inside he would just be passed from the outside. At some point it’s simply impossible to defend against a faster car, this was that point.
