All the examples of the articles are good, but there are two many to learn and remember. I follow one and only one rule when I ride my bike. Assume you can get killed at every time and do not trust anything.
Sometime I see people wanting to turn left, raising their left hand and then turning without never looking backward to check if the following car is not trying to pass them. These people are crazy and want to die. Always look backward before doing anything else or if a car is approaching.
Many people assume that as a bike rider they have rights and as a result they should be respected by cars, and end up in dangerous situations because of that. Do not trust anything if you want to stay alive
