Unfortunately, not everyone can ride a motorcycle or lives where the other motorists are friendly (or at least not-hostile) to motorcyclists. Many also consider it beyond their tolerance for risk.
I am really lucky to live where people are happy to accommodate motorcycles (cars make room for motorcycles to split lanes when we have slow moving traffic) and I use one to commute to work everyday. I do sincerely wish more people could share in the joy of riding a motorcycle :-)
However, I am aware that there are places where people are hostile to motorcycles. I just hope that some day things get better.
