Reserve F1 driver and founder of Meuze AI @jackdoohan33's workflow is absolutely brutal.
After spending the day at the track gathering data, he flies back to the team's factory and works in the simulator from roughly 6 PM-3 AM, testing setup changes and ideas that engineers couldn't explore at the circuit because of F1's overnight work restrictions.
He then goes straight back to the airport, flies back to the race, and briefs the engineers and race drivers on what he learned.
Because the simulator is based in the UK and the races take place around the world, he's constantly battling jet lag and sleep deprivation, while still providing feedback accurate enough to influence the setup of his team's car.
