Bicycles are pretty bad. I think some cyclists like to intimidate car drivers, or at least it seems that way sometimes. Motorcycles are also pretty bad, and it seems as if these days they are not scared of cars anymore, which is somewhat stupid on the part of the cyclists', because, an automobile can easily kill them. I'm not directing this at anyone in particular, because you do have many cyclists that follow the law to the T and drive defensively. So, make long story short, yes, cyclists do concern me at times. Furthermore, pedestrians also do things they should not as well.
