There are so much love for bicycles. I'll offer something from the other side that people who drive. What I really find it scary is that cyclists often take the road as they wish and then block dozens of vehicles, or do something else that might seem to be quite normal from their perspective, but nevertheless is dangerous from drivers' perspective (e.g. suddenly get into road from sidewalk, are you going to cross or not?)

Basically, if the road you are cycling on are not reserved for cyclists, I'd say you are putting yourself and other people in risk. My city has a lot of cycling lanes but unfortunately not every road has one.
