Injuries or deaths don't always have to mean bad design or implementation.
If another car shoves over yours, hitting your head... there's not much to be done about that.
That being said, I don't think deducting points for 'relative safety' is the way to go.
A clear set of rules have been put up, and every driver has the choice to get in the car. That's that.
I know many people will disagree, but to become a hero (which most of them want), one will need to take real risk.
That doesn't mean people will have to die, but it does mean that a 'balance' needs to be found.
Because in the end, staying home watching goldfish get old will always be safer than driving an F1-car...
The last death in F1 before Bianchi was... Senna, right?! Bianchi was sincerely tragic, but no protective measure will do when you glide under a standing 4 ton truck...

.
That means that in one of the most dangerous sports in the world, the last (maybe, perhaps, who will ever know) preventable death was 23 years ago...
