To be honest I can't get sad over it, these guys were racing drivers they lived their lives doing the thing they loved to do, they knew the risks and were prepared to take and accept those risks, I could name a dozen other racing drivers who have been killed doing the sport they loved since then and not one of them choose to quit or not take up the sport knowing the risk they were taking, even Senna's nephew wanted and still does want to be in F1....
To be honest if the sport was completely safe I don't think people would bother doing it, or even watch it.....
It is the danger and the rush of adrenalin that drives them on, take that away and you have nothing, I have been on so called extreme rides at theme parks, but knowing I was completely safe made me feel nothing about the ride, other people screamed but I just got off at the end thinking, what a waste of money....
I agree with Sir Sterling Moss modern day F1 is far to safe as it is.
