I think they have as much of an uphill struggle in reliability as merc have which overall chassis performance.
One of their cars consumed and entire racing years worth of critical parts in one single race weekend.
By the letter of law (rules) this becomes the worst display of reliability in F1 in so many decades.
The rules are very stupid of course, one rule breach = two race weekends ruined is just silly, but then the entirety of F1 is stupid.
Be F1:
"Should we let teams use active suspension to make car design and running much simpler and better for the sport!??!" NO!
"Should we think about adding sprinklers to the track to make artificial rain that we always red flag anyway!?!?!?" DAMN RIGHT
"Should we propose an idea where the leader has an anti-drs to slow them down!?!?!" HELL YEAAAHHH!!!
F1 is meme
