since the OP asked a legitimate question, I'll try to give an honest answer.
From my experience, the average rider on the road does not have a sufficient level of skill to manage an unexpected scenario. Fundamentally, sending a person to ride around a parking lot for an M1 exit weekend, then setting them free on the road is woefully inadequate. (I have similar distaste for our car licensing system, but that's another story). I see lots of riders with many years of experience, yet insufficient control. As a student of Keith Codes said, they did not have N years of experience, they simply have 1 year of experience N times.
How do we improve control? We improve confidence and skill.Confidence and skill come from understanding a motorcycle's response and limit. How far can I lean? How hard can I accelerate? What about in the rain? How hard can I use the front brakes? These skills need to be reactions, not though-processes. Reactions come from training, just like any sport.
IMO, all advanced motorcycle training should take place at a track, with proper supervision/coaches, medical staff, and leathers. Not in a parking lot. This type of training should be mandatory, regardless of what type of motorcycle you ride. The problem is, how far can you honestly expect someone to ride a motorcycle in an environment without proper safety? Get the guy in jeans on a 800 pound bike to start locking up wheels or finding out where his chrome running boards are in a parking lot? No Thanks. I realize renting a track is expensive, but its the place to go to explore limits. A controlled environment.
Most will sight cost, but cost is relative. When you are lying there in the hospital for a week or a month, how much will you regret not spending the $300? Most riders improve more in 1 day on the track than a year on the street. I encourage all riders, fast or slow to take a day at the track.
The silver lining is skill stays with you for your whole life, regardless of what bike you have. Conversely, it is interesting to see how much people spend on chrome, HIDs, pipes, fuel controlers/etc, but don't invest in skill because it is 'expensive'. Racer 5 offers an excellent program with great value, FAST school is also good.
Not everyone wants to race or do trackdays, and that is perfectly ok.
