   Seems wild that they can code and deploy an update of a critical-seeming component in the field like that. I thought such a firmware update would need extensive QA in the lab, along with root causing why this bug slipped through their processes anyway.

   But maybe that's the difference between shipping a controller for F1 versus shipping one for an industrial or consumer product? shrug.

      I'm wondering how good the simulators are. At the start of the season, they were still learning the systems trying to figure out why they were losing power in the straights. So depending on the driver, issues may or may not become apparent. That's like trying to debug why an email can only be sent to a recipient less than 500 miles away.

         Anthony Davidson who is the Mercedes test driver said that the teams can simulate these scenarios and it seemed that the Mercedes cars were not affected so it seems that other teams hadn't done similar testing in various scenarios.

            One of the mercedes literally broke down and did not finish the race. They might not have faced the issue during the first time they went out in that race but Merc reliablity has been very shaky. And ofc Ant will talk only good things about Mercedes. But this is not the type of things they use the driver simulator for, it is to help the drivers train. These types of issues don't make sense to spend simulator time on with the driver in it

               Seems a lot better place to learn than in the middle of the race and earning $0 for the race. Isn't that the entire point of a simulator to learn things that are too expensive to learn in the real world?

                  There's more than one type of simulator, and F1 has certain 'spending caps', after a spending war bankrupted bunch of teams.

                  Wind tunnel time and aerodynamics simulator time are included in the cost cap, as are car parts and most staff (but not driver salaries, travel or marketing)

                  Drivers can spend all the time they want in standard consumer sim racing rigs, practising the tracks. But when it's the type of extra-high-fidelity simulator that lets you make the car better - that's subject to the cost cap.

                     I assume someone is already offering an extremely high-fidelity CFD simulator (or a wind tunnel) to help companies shoot awesome videos of their cars, for purposes of including them in TV spots, of course.

                        CFD simulations came at around 2010. Redbull had the best of them, that's why they took over from Mercedes-McLaren those years.

                        I worked on engine and powertrain simulations, and my compiler was used for vehicle and driver simulations. This was built for Honda, but Honda left, bought by Mercedes, and won them several championships.

                           In fact there is a very specific cap on CFD simulations beyond the normal cost cap, to prevent an HPC arm race. Used to be an actual flop cap, but of course teams found way around it, now it is more complicated.
