   A question for someone who knows more about F1: Is this firmware shared by all cars? Or some local server at the track the cars connect to? Why is F1 able to control individual cars like this? The article is very light on details as to what exactly is going on...

      The firmware situation is mixed. The ECU hardware is a standard TAG700 from McLaren. Basically these are software-defined ECUs where you can do whatever. However, FIA has some rules on what you're allowed to modify and has some "compulsory" software in there for monitoring and competition regulatory reasons. It appears there was very limited testing of this module in wet conditions which seems to have affected a lot of vehicles. (I work in Motorsports)

         McLaren sold McLaren Applied, the makers of the TAG700, in 2021 and it’s now known as Motion Applied.
