i think this is just the same in towns and cities, places of work..some people have manners..some people are just ignorant..simple :| . if someone lets me out when i am driving..or commuting on my bike..always say thanks..even if a car attempts to go then thinks better off it when on my bike i always "nod"{ i might be swearing like a trooper in my mind } to say thanks for seeing me...manners and courtesey in all aspect of life create harmony and can diffuse situations.
