Simple Question

When a car hits a person or a bicycle, the car's fault is usually higher. I understand that, but it's strange... If a bicycle is going the wrong way on a narrow road and collides with a car (both are moving), would the car's fault still be greater? 🤔 Bicycle rules have increased and changed, so I'm not fully aware of them, but I know they can only go in the same direction as cars, so I wondered if the bicycle would be at fault if it was going the wrong way, after watching a traffic accident video on X.
