Why are some motorists so angry towards people riding bikes?

Why are some motorists so angry towards people riding bikes (and other road users to boot)? Here is a range of psychological and social factors that drive the irrational animosity towards people who are often just making use of the public highway like anyone else. Any of these ring true?

Displaced Anger: Drivers may vent their frustrations on other road users due to anger from other situations in their lives.

Sense of Entitlement: Some drivers feel that cyclists, by not paying road tax or having the same obligations as motorists, are not entitled to use the roads.

Perception of Disrupted Order: Some drivers feel cyclists disrupt the established hierarchy of the road, where cars are seen as the dominant form of transportation. Cyclists may be perceived as cutting in line, riding on the pavement, or going the wrong way on a one-way street.

‘Roads are for Cars’ Mentality: A significant portion of drivers believe that roads are primarily for cars and other motorised vehicles, and that cyclists don't belong there. This can lead to hostility when cyclists are encountered.

Conflicting Rules: There can be confusion and frustration about how the rules of the road apply to cyclists, leading some drivers to believe cyclists are breaking the law even when they are not.

Misinformation and Stereotypes: Some drivers hold negative stereotypes about cyclists, fueled by media narratives or personal experiences, which can lead to prejudice and aggression.

Traffic Congestion: Some transportation experts believe that traffic congestion contributes to driver frustration, which can then be directed towards cyclists.

Culture Wars: In some instances, a wider ‘culture war’ rhetoric can be used to demonise cyclists, further fueling aggression.

Comments are open, let me know your thoughts. As a car driving train using bike riding pedestrian I like to think this gives me a broad perspective and how people travel and the challenges they face, and as a result I tend to avoid the anger and frustration displayed by some other people. So if you find yourself getting hot under the collar with a certain type of road user, maybe give that mode a transport a go yourself. It might save you a visit to the doctor.
