I just sold my bike, and am bikeless for the 1st time in 25 years. After 40 years of riding, the combination of distracted drivers and 'seasoned citizen' drivers in our area have made it too dangerous to be enjoyable. It was a hard thing to do, having been border to border and coast to coast on two wheels over the years. I love riding and miss it... I might buy another bike if we move to greener pastures when we retire in a couple of years.
If you've never experienced the thrill of a high performance motorcycle, it's nearly beyond comprehension. If you've driven a car with 600+hp, you might have some idea. It's a hard thing to temper when you're young and invincible, and unfortunately most riders don't seek out the training and knowledge to develop the skills necessary. It's a lot like shooting in that respect...
Eventually, I got myself on the racetrack and drag raced and road raced bikes for a number of years. It allowed me to use my bikes to their potential in a way that was simply not possible on the street, and that greatly improved my street riding. It developed my skills, and it reduced the desire to be imprudent on the roads by allowing an outlet for the 'need for speed'.
With my patrol area encompassing several of the more popular 2-lane mountain roads for motorcyclists, I investigated plenty of crashes, and many fatalities. When I made stops for speed, I encouraged riders to seek out training, and get their thrills on the track... a track day was cheaper than a speeding ticket after all. And much less expensive than a trip to the ER, or worse.
