wrong you need a good # 2 to cover any possible strategic calls (undercut, overcut, etc.) from your opponent.
and i makes it more likely to become champion with a good #2 (see mercedes the last few years with bottas) as when you have 2x #1 stealing points from eachother. (of course if you have a opponent/another team that is close to you)
and if you are #1 driver and you are sure to take more points as your #2 driver it becomes easier to win a championship.... or why do you believe Mercedes played the switcharoo card a couple of times between Bottas and Hamilton, to ensure Hamilton could get the maximum points neccessary to become Champion.
but let us return to the topic because this is a in season discussion and we are at Silly Season 2020/2021
