Your last paragraph including something that resonated with me. I do think some have come to view cycling as something that is elitist/hipster, at least as a distinct subculture away from the mainstream - with its own lingo and uniform.
I trigger the record function on my dash cam when I worry that I could have done things better. Watching the footage has helped me find opportunities for learning and development.
I believe that good driving requires empathy. Empathy for other road users - pedestrians, horses, bikes, cars, whatever - makes you a calm, courteous and safe driver.
Empathy requires a lot of brain power - you need to be able to analyse your surroundings and anticipate your needs and the needs of others, in real time and at speed . I reckon most people lack the discipline to free up the head space required to be empathetic. A proportion will lack the head space to do much more than just drive the car, but that might be my cynical misanthropy creeping in.
This too shall pass
