I understand your frustration but not riding a motorcycle is not the solution. Getting a proper gear when you are riding, a better training from a proffessionals like riding academies, being aware of the danger and taking necessary precautions.
You can not give up something because of others wrongs. If everyone riding crazy that doesn't mean you have to ride crazy too. What should be done is riding safe, with proper gear and try to set an example of yourself.
You might say that they don't listen. What you are telling is not to them anyway. If a person can change their mind about riding or not riding a bike with a proper warning, then they can definetly be able to listen for safety riding.
So the question is :"Why baning motorcycle while you can make it safer and a more educated community?"
This way maybe that people who doesn't listen, may get an example and it spreads out through biker to biker.
