Cycling without lights and texting while driving is only really dangerous to the cyclist in question though, not really for other cyclists.

Turning without signalling is a bit of an annoyance though, I run into that fairly often.

Kids cycling two by two is also frustrating because you can't overtake, but it isn't directly dangerous.

The fact that cyclists here in NL can break the rules with impunity and still stay pretty safe is probably a consequence of how good our infrastructure is, imo
