Recently, there has been a push to go car free. The alternative is bicycling around town. This is a great thing for the environment, the wallet, and health. I am 100% behind this movement.
However, I got a bone to pick with the bicycling culture. It's about the basic of bicycling that people either are not familiar with or forgot.
1) get a bell/horn - I don't understand why bicycles don't come with one. Every bike sold should have one. It warns drivers and pedestrians that your are coming. I don't know why every person on a bike expects both drives and pedestrians to watch out for them, but not the other way around. GET A BELL AND USE IT!!!
2) follow traffic rules - so many times I have seen bikes on the road or on the sidewalk and not follow either set of rules. When you are on the street, safety should be your priority, and the responsibility on the biker as well as the driver. When you are on the sidewalk, be nice to pedestrians. People on bikes seem to want everyone to get out of their way.
3) get a basket or rack for your stuff - I don't understand why this is not part of the commuter bikes as well. If you are going to buy stuff, put it in the basket in front or rack on the back.
Where I grew up (until I was 10), these things were very common because biking was how everyone got around. However, it seems that the biking community in the US still has a lot to learn.
