This is what happens when Mad Max chases off the manufacturers for tiny teams FOM can bully. Too many pay-drivers for the number of seats. (At least Simona left quietly.) They need to bring back BMW money.
How many steering wheels though? Imagine the radio conversations: "Brake now, steer here, no! You missed the apex..."!
Actually, one can operate the brakes, the other the throttle and the man in the middle can do the steering bit.
