I've experienced this same anecdote in similar situations for the past 20 years as well. There has been a long push by auto manufacturers to make anything other than cars that use the roads seen as both illegitimate and illegal. For example, see the history of Jaywalking laws: https://www.bbc.com/news/magazine-26073797. Starting around 1920's the auto-industry encouraged laws around the US to make crossing the street illegal. These laws have the downside of making car drivers feel entitled to the road.
Cyclists and other non-car users of roads have a deep hole to climb out of to change these laws, and to change the perception that streets are only for cars. Infrastructure is probably the only real mechanism we have that can make tangible changes, that don't allow the personal feelings of car drivers to get angry at being inconvenienced by cyclists and other road users.
We need to slow down auto-traffic and encourage more non-vehicular use of the roads, while making those roads safer for pedestrians, cyclists, scooter riders, skate boarders, etc.
