I roll down a rode on my commute every day that has a sweeping blind "S" curve of which Northbound traffic tends to misjudge in terms of how fast it can be taken.
Over the years I have ridden/drove past accidents that occured in the afternoon there that produced numerous casualties.
Needless to say this tempers my inclination to take this curve with any degree of abandon. I usually just slow way down and keep to the extreme outside edge when going either direction.
I get this picture of a dead biker laying unattended on the edge of the road while paramedics work on his partner. This mental snapshot easily overcomes a desire to take this curve with a challenging attitude.
I am over 50 so I no longer have any naivete as to my own mortality.
Its amazing how your average 18 year old does not. Sadly, more of them would survive accidents if they had a better sense of their own "mortality"
Lots of wannabe evel knievals amongst each new generation of teens.
