I am aware of the necessity for awareness when riding, as I have been riding since I was 9 (starting on dirtbikes, obviously). I have owned 5 different road bikes, the last being a zx-11. The only two "accidents" I ever had both occured under 5mph, with only me on the bike, and involved the bike simply going over (once because of a patch of soft dirt on a back road, and once due to a puddle of oil in a parking lot). I am mostly looking for ammunition to help educate my wife that motorcycles aren't the guaranteed death warrant she has come to see them as. I am not entirely sure how she came to that conclusion, since I had a bike when we met, and she actually enjoyed going on rides, but even if it doesn't result in my being able to get another bike, I'd like to help her change her attitude.
My best friend has a zx-11 and a zx-9. He has gone over once and it was minor. He has also put literally hundreds of thousands of miles under him in his 48 years.
The thing about bikes is that it takes skill AND a natural hand-eye coordination and certain mindset to not get yourself killed. If one is in that group, one is fairly safe on a bike, irresponsible behavior notwithstanding. If one is not, they are an accident waiting to happen.
An oversimplified generalization I use is this: If you were always the last to be chosen for sandlot sports, or if you found you hated or kept falling when riding a bike, you might want to avoid owning a motorcycle - permanently.
Likewise if you find yourself drinking and driving...
