Specifically, the page about red-light running, which if you scroll down lists numerous sources showing people on bicycles do not break traffic laws more than drivers: https://cyclingfallacies.com/en/11/people-break-the-rules-wh...
People think cyclists break traffic laws more because cyclists are a minority outgroup, and like any other minority outgroup, negative behavior and attributes are exaggerated. A whole slew of observational biases come into play.
The absolute favorite thing drivers love to shriek about is cyclists not obeying stop signs and stop lights. Except that in urban cities, the most common cause of crashes is usually doorings and "hooks" - where the driver passes a cyclist, while braking and turning - something that is almost impossible to avoid because a car can out-turn and out-brake someone on a bike, and the situation was initiated by the driver. Doorings? You can tell people "ride outside the door zone" but that usually ends up subjecting you to all sorts of abuse by drivers, including "punish passes", which turn into collisions when drivers misjudge the distance and hit the cyclist instead.
The amount of hatred drivers have for people on bicycles is astounding. Even people like the head of the British Automobile Association described the attitude drivers have as being similar to racism: https://www.huffingtonpost.co.uk/2012/11/16/cyclists-abuse-r...
There's also the ever-popular self-loathing bicyclist who loves to criticize and victim-blame other cyclists. It may come as a surprise, but victim-blaming by members of a group is done as a psychological self defense mechanism. Being struck by a driver is something that by and large you have no control over; cyclists obeying the law, riding prudently, in a straight line, on a straight road, wearing high-visibility clothing, etc still get plowed into. That's scary, so people invent reasons why the victim was at fault - reasons that coincide with steps the victim-blamer takes that they think protects them.
