This is Stroll commenting on the rumor that he was quitting and going to the pro tennis tour:
I would re-write that just slightly:
Well, if I'm going to stay in F1, I'm going to need to work on my driving a little bit because I don't think I'm quite at that level yet. I mean, I like to think I'm pretty good. But I don't know if I'm ready to go up against Verstappen and Alonso just yet.
Realistically, there's NOTHING for him to work on. At the F1 level, you're beyond 'working on your driving'. It's now raw talent. You've either got it or you don't. He don't!
