Two questions here, really. Playing about with statistics to compare risks doesn't really answer either.
Question one, are you more likely to be in an accident in GA than driving (or racing) a motor cycle.....
Question two, are you more likely to DIE in an accident in GA than .....whatever.
And then somebody observed that if you have no petrol (gasoline) left, you are less likely to be toasted.....
To what conclusion does that lead the sensible risk taker? Fly an aircraft with NO PETROL and no engine, either. Obviously, take up gliding. General Aviation - (I do have 1200 hours power flying) is definitely more complicated and more dangerous than gliding (I have 1800 hours in gliders). But most power pilots come to grief because of an attitude problem; eg thinking a single engine small aircraft can reasonably used for business - or thinking I MUST get back to the home airfield because my car/wife/girlfriend is there.... or thinking if I throw this aircraft around with a few aerobatics, my passenger will really be impressed, etc etc.
There are old pilots and there are bold pilots....
