While there are a lot of posts in this thread indicating some members' increasing uneasiness and lack of desire to continue riding, if you look closely there are a good number of posts from members who acknowledge the risks and choose to continue to ride. Like you, I've spent plenty of time on racebikes and streetbikes alike. I tend to ride for both the thrill and the emotional detachment from the drudgery and pressures of the daily grind. I don't ride cause it's cool. I don't ride to impress chicks. I don't ride to earn a new patch on my eather chaps. I ride cause I love it. I ride cause it switches on a level of focus that is a high unto itself.
When street riding becomes boring to me, I will become concerned about a lack of focus. If you're using a bike as simple transportation, then it's time to climb back in your 4 wheeled cage and zone out.
Are bikes dangerous? That's a loaded question.
The odds of being in an accident/collision on a bike are probably similar (per mile) to the odds of being in a collision in a car (I haven't seen any figures, but I'm guessing they are close).
The odds of being injured, however, in that collision are FAR greater on a bike than in a cage (car).
There are circumstances that affect our survivability (in a car or on a bike) that we have no direct control over. That's for sure. I had a Buick fly over a divided median and crash through the front windshield of a van I was driving. Hard to have much in the way of control over something like that. I could have just as easily been riding a bike that day. Would that have been the fault of the bike? Not hardly. But I might have been killed had I been on a bike - or I might have been able to squeeze by without contact. That is the part where it gets odd. A bike is more dangerous, but in some cases can be a better instrument of survival.
Odds. Rolling dice. Luck.
I don't really believe in luck, but in the world of statistical analysis, there is still a major component of "variation", "noise", or "deviation". A normal amount of deviation is expected and attributes towards the bell curve. Samples that fall outside of the curve constitute the "noise".
Hopefully we all will find ourselves more often on the desirable (safe) side of the curve.
I rode my R1 last night for just a little while. What a riot.
