You're absolutely right! However, the main difference is that cyclists pose much less danger to other road users compared to motorcycles, cars, or trucks. Of course, there are accidents where a cyclist collides with a person and causes serious injuries, but when a motorcycle, car, or truck collides with other people, the consequences are dramatically more severe. This isn't to justify cyclists doing whatever they want in traffic, but they usually only endanger themselves. If they collide with a car, the car might get a dent, which can be fixed within a few days, whereas the cyclist might struggle with injuries for weeks, months, years, or even a lifetime.
