In April, the car itself went partially open source, with a complete set of schematics and specifications and an invite for engineering bugfixes. According to them, it's the first time a racing team has done this. Sounds likely enough. The latest patches to be released were a tripling in fin size and a switch to steel brakes because carbon fibre would explode."
