I think parting it is the team is finally realizing that Carlos is the overall better driver, and they shouldn't put all their eggs in one basket. Don't get me wrong, Charles has more raw talent imho but Carlos is more complete and doesn't just crumble under pressure.
He's not doing that bad all things considered.. but yeah. Not having a great 2023. Still ahead of Sir Lewis most the time and what the only real threat is McLaren or something? Perez is racing hard tho that's for sure
