A Dozen Deadly Motorcycle Safety Myths with my comments for flavor..
These are all expanded upon in the link above but here's the rundown:
Myth 1: Other Drivers Don't Care About Motorcyclists - Actually, other drivers don't care about other drivers either so its not really any big news.
Myth 2: Loud Pipes Save Lives - The only way loud pipes would work as a safety feature is if they faced forward and then the bike would look ridiculous, breathe like crap and probably still offer no greater safety. Loud pipes annoy people, period.
Myth 3: Motorcycle Helmets Break Necks - And seat belts break sternums if the impact is hard enough. If your neck is going to get broken by your helmet whipping around then you have almost no chance of survival in the first place.
Myth 4: Helmets Block Your Ability to See or Hear Danger - You can hear a car that's about to hit you? No, you can see them and that's why situational awareness is so important. Keep your head on a swivel and know what's going on around you, your helmet is no impediment to using your senses at all.
Myth 5: A Helmet Won't Help in Most Crashes - Um, what? I've been three motorcycle accidents over the last 20+ years of riding. If I'd not had a helmet on in any of them, I'd be a vegetable. At best.
Myth 6: A Helmet Will Leave You Brain Damaged in an Crash When You Would Have Simply Died - More likely you will be paralyzed and alive instead of being dead because your head will not have been crushed.
Myth 7: A Skilled Rider Should Be Able to Handle Almost Any Situation - A skilled rider is prepared, a skilled rider is dressed properly, a skilled rider wears a helmet because he/she knows that you can't control every situation. Accidents can and do happen and it is far, far better to be prepared for the worst than to hope for the best.
Myth 8: If You Are Going to Crash, Lay It Down - If you lay it down then you have crashed. Simple as that. Bike brakes slow you down far more effectively than sliding on your side.
Myth 9: One Beer Won't Hurt - Legal limits mean nothing, if alcohol impairs your senses then it can be the difference between crashing and having your wits about you enough to avoid it in the first place.
Myth 10: It's Better to Stay in Your Lane than Split Lanes - If I couldn't split lanes then I might as well drive my car for all the good it does.
Myth 11: I'm Safer on the Street than on an Interstate - The interstate has everyone going the same direction, streets have side streets, traffic entering and exiting and all kinds of other distractions and obstructions. This one is just stupid.
Myth 12: A Skilled Rider Can Stop Better with Conventional Brakes than with Anti-Lock Brakes - Anti-lock brakes pulse far, far faster than any human could ever think to pump their brakes. There's a reason every single test shows anti-lock brakes annihilate conventional brakes. Not only for braking distance but maintaining control during the hard braking.
