8 of us so far.
My team is ready. Errrr, ready... to change after FP in Bahrain.
Remember that team changes are completely free even after the first GP and until qualifying for the "Formula 1 Pirelli Gran Premio Del Made In Italy E Dell'emilia Romagna 2021" (Yes, I mean Imola). And after that there are still 6 changes allowed "for free". A secret: last year I did more than 6 changes, and nailing the team for the last races was worth the penalty points and then some!
They changed Vettel's drawing! The hair is gone!
