I have legitimately never seen people on bicycles disrespecting road laws unless those road laws enforce something that is unsafe

Come to Philly where you can see guys on fixies blowing through red lights without even looking left and right first. Or go anywhere and see people (of all ages, surprisingly) riding against traffic on the wrong side of the road - something that is the perfect blend of illegal and stupid, although not quite as illegal and stupid as the first thing I mentioned here.
