even if that were true (statistically it isn’t), unlike with a plane roads aren’t so tightly controlled and other drivers are barely competent. head-ons happen all too frequently and i’m sure one of the victims is ... a safe driver.

driving isn’t unsafe because of your own (self-assessed) skill, it’s unsafe because of that other 50%.

no matter how safe of a driver you are, you should be worried.

I should write a treatise in every post :o)

I'm aware that people over-estimate their skill, I'd have been inclined to say "in the top 20%" otherwise, lol. Whilst my reaction time has slowed slightly, and my focus deteriorated a little with age (IMO), I've been driving cars for 25 years without an at fault collision (taxi driver hit me when I braked hard to avoid killing a dog -- we were sub 30mph otherwise I'd have chosen to hit the dog). Have avoided some accidents for sure. I also hold a full motorbike license, have driven minibuses and car&trailer pairs. I'm aged enough to have calmed down and having ridden motorbikes feel I've much more road awareness than the average driver.

Also, I considered head-ons, etc., where the injured party is not at fault - but whilst they increase the risk an experienced and competent drive can avoid some collisions, mitigate the harm of others, and will nonetheless reduce their chances of being in a collision from their side. If 50% of injured parties are the cause, and I can reduce that 50% by 50% then I've still reduced my chance of being injured by 25%.

Does anyone think that doesn't put me in the bottom 50% for risk?

Still, the point stands that I expect aeroplanes to be better maintained and have more redundant and fail-safe systems than a car; and expect pilots to be better trained and more competent (prevented from driving drugged/drunk/tired more than truck/car drivers, etc.) than the average car driver. So, aeroplanes only having the same per-mile safety as cars is [would be] terrible.

skill != safety, because how much of a safety margin you leave generally swamps most of the effect of skill. And your safety margin reduces the effect of other drivers' stupidity.

And I hate it when people say "statistically that isn't true". How can a fact about an individual be statistically not true? Is it statistically true that I have 2.4 (or whatever) children, even if I have none?
