It has nothing to do with you being on a bicycle. I see it all the time in different modes of transportation. Some people just assume their commute (or time) is more important then yours and will do anything they can to get ahead of you. The same type of person will do it in a car, while they're riding a bike, while they're walking, shove ahead of you in line, or getting on a bus or an elevator or a train, etc., etc..



I had a guy on bike pass me several times on a bike trail then slow down. So I passed him on a straight section and went fast enough, long enough that he fell far enough behind to not bother me the rest of my trip.


It's a strange personality type.
