I have friends that seem to have settled into a lifestyle that steers clear of dangers and I have watched as they have lived, from my point of view, very insular lives lacking that rare excitement that the world has to offer.
Riding motorcycles in urban areas is betting your life on other people's awareness.
I've owned a motorcycle more years than not since I was 12 years old. For some stretches of that time the motorcycle was the only motorized transportation I could afford and I relied on it (even in the winter on icy streets) to get to and from work and college. And I've dropped motorcycles a few times, slammed into the back of a bus once (icy), but otherwise have been okay.
I'm older now and less desperate and so can afford to take the motorcycle out only on joy rides where I can pick the weather and the destination (out of the urban areas). And not to stereotype bikers too much, but I might add that I have never owned a sport/racing bike. I am more like the gentleman motorcyclist of an earlier era, ha ha.
Obviously the above has made riding much safer. I don't think I could completely give up riding though until I become physically unable to.
I don't offer this to refute your experience but rather to complement your comment with an example of a rider (turning 60 this year) that has not been seriously injured and has enjoyed the "sport".
I don't ride my bicycle on the roads for the same reason.
