Well everyone has a bias as everybody has a different perspective on the world. That you can't appreciate biking (through your own choice or no), makes yours particularly "thick" (in the context of biking).

I also think its not unusual for people in this thread to be able to drive, and thus the need to portray how bikers are seen largely unnecessary (in my view). Drivers are the majority, and even keen cyclists will probably be drivers too.

As an occasional cyclist, I get particularly annoyed with bad cyclists when I'm driving, as I feel they bring me down with them by association.
