It's also important to note that it's only a fairly recent development that fatal injuries in F1 are a rarity. The previous last death in F1 was Ayrton Senna in 1994, with Barrichello being injured and Roland Ratzenberger dying that same weekend. Ayrton was a big proponent of driver safety, and his death sparked a huge push to improve safety in the sport.

It wasn't until 2014 when Jules Bianchi crashed in Suzuka that F1 saw another death during a race. Now, a biometric sensor probably would not have helped Jules, but it may have alerted the medical team to the seriousness of his injuries. Oximetry and heart rate may not have indicated much, but I think it's a great first step towards other sensors that could eventually be incorporated.

F1 tries to be at the forefront of automotive technologies. Driver safety always has been and should be a huge part of that.
