Googling it, I found a second one in London with the same methods (surveying CCTV footage of multiple intersections) and they get the same findings
In both:
- Motorists break way more traffic laws
- Motorists mainly break the law for speed or convenience
- The infractions by motorists are generally more serious and pose a threat to others (the main one is speeding)
- The main one cyclists break is riding on the sidewalk - which is because of cars, and it doesn't happen when there is a bike lane
- The second one is turning right on red without causing inconvenience to other road users

For the danish government report unfortunately they moved it and I can't find it anymore
