In Formula 1, the Virtual Safety Car was introduced following the fatal crash of which driver?

The virtual safety car in Formula 1 was introduced following the fatal crash of Jules Bianchi. Bianchi, a talented young driver, passed away in July 2015, nearly nine months after his accident at the Japanese Grand Prix in 2014. Bianchi's crash occurred under yellow flag conditions, with a recovery vehicle on track retrieving another car. The introduction of the virtual safety car aimed to improve safety during races by electronically limiting the speed of all cars on track in case of accidents or track hazards, thereby reducing the risk of further incidents like Bianchi's tragic accident.
