I take your point on the prangs being minor. However, it is clear that the driver is a passenger if he commits a minor mistake on that stretch of tarmac between the tunnel and the Nouveau Chicane. Nico Rosberg was uncomfortably close to a head-on collision down there. It is a roll of the dice whether you get seriously injured into that particular wall. Thankfully, that didn't happen today.
In 1994, Formula One said "never again" when the lives of Roland Ratzenburger and Ayrton Senna were lost at Imola. I personally don't think that the threat of death is an integral part of racing.
Whereas I like your post and can see your point, I suspect that not to many drivers would agree with - OK, maybe Barrichello.
