They’ve had the luxury of being able to switch focus to next year since May already.

Well between the penalty and the fact that they naturally get less time because of their championship position, teams like McLaren would have had almost 50% more testing time. This and the fact that updates on this year’s car carry over to the next in my opinion nullify the advantage RB got from stopping upgrades early. What is an issue for other teams is that with the design team that RB has, I back them to make better improvements than the others even if the testing time allocated for next year by all the teams is the same
