There's nothing inconsistent about that. Cars are multi-thousand-pound multi-hundred-horsepower machines traveling at deadly speeds, with an ability to kill multiple people with a minor movement of the wrist.
Someone riding on a bicycle going 22km/h has, without exaggeration, less than 1% of the momentum of a car going 60km/h, and 1/2500th the amount of power. They have orders of magnitude less capacity to cause harm to anyone.
Appropriately, and reasonably, they bear a lot less responsibility on the road and can be a lot more flexible with the rules. Similarly, pedestrians have even less capacity to cause harm so they enjoy even more flexibility. On the other hand, semi trucks have more ability to cause harm and so have to contend with even stricter regulations, licensing etc. Commercial aircraft, stricter still.
Traffic laws and infrastructure in North America are almost entirely put in place for the benefit of cars and ignore the existence of all other modes of transportation. I submit that the North American legal and physical environment are just flat out broken, unjust and illogical when it comes to cyclists (as well as pedestrians to an extent). It really is reasonable that someone on a bicycle should enjoy more flexibility than a 3 ton SUV. The fact people are so upset that cyclists would behave any differently than cars despite being completely different is a great achievement of motorists and the auto industry to manipulate our culture, to force everyone to navigate society on their terms for the benefit of cars, to the point of insanity.
The fact that you refer to bicycles as "toys" reveals that the real issue you have with cyclists is not the bullshit story you present, where you pretend that cyclists doing the same exact thing as every motorist does - rolling through stop signs - presents some danger to society. You simply hate cyclists outright, you don't care about their safety, and think they don't deserve any space on the road at all. You just don't care about people who want to, or have to get around without a car. Your motivations are selfish and you should feel bad about yourself.
