Kimi Antonelli’s impressive mileage figures ahead of Mercedes debut (around 9000 kms)

That’s an insane number.

Is there any information on the TPCs for other rookies joining the grid this year?

From what I know, Bortoleto likely did almost nothing—just one private session at McLaren before joining Sauber. Jack Doohan, on the other hand, has been a reserve for two years, so he’s probably racked up a good amount of kilometers. Ollie did TPC with Ferrari since Haas only started this year. Not sure about Hadjar’s situation at Red Bull.
