Bro, blue lock characters a F1 AU would be so good. Like the theme of blue lock is to have an ego, and one of the main things about a formula 1 is their ego to win.
Like one of the DTS quotes is literally, "there's a difference in believing you can win and knowing you can when."
Only drivers who have that ego to win are considered World Champion material. I honestly think this can really work for the blue lock boys.
The AU I was thinking would be that Isagi is in his rookie season of F2, and his teammate is Kaiser, who is the favored pick to be the F2 winner.
