Wow. I just assumed it wouldn’t be firmware because going from making a fix in 50 minutes to having cars flying at hundreds of miles per hour on that firmware is kind of nuts

It's a pretty intense sport & that kind of timeline is fairly common. They'll do a full car rebuild right before the race, if the driver's had a crash in the session before it. So, the driver will be approaching a corner at 250kph+ in the full knowledge that the brakes were wired up to the pedal just ten minutes earlier. They'll make brake-balance adjustments on the fly in the car as they're speeding down the straightaway.

I think the drivers have some extraordinary capability for trust, because the chain of people who need to have got their job correct for that brake pedal to work in that moment is in the dozens, and the consequence for any of them getting it wrong is a particularly violent crash.

Move fast and try not to break things.

Every race is a different car, maybe a different engine, with different software, basically.
