Maybe because it's because within the three groups (cyclists, drivers, pedestrians), cyclists are the only ones who haven't got their own infrastructure.
If cyclists had 90% of the road, and cars were forced to share the remaining 10% with pedestrians, everyone would be complaining (with reason) that's it's incredibly dangerous
