I wouldn’t say cyclists are morally superior, but IMO certainly commuters and roadies, from bitter experience, have a broader perspective and awareness than your average joe, about the dangers of a car-dominated society (pollution, congestion, obesity, unpunished agression/bullying).
A broader perspective generally brings wisdom… so maybe we’re wiser rather than morally superior.
I do think including cycling in the driving test would do a lot of people a lot of good in terms of helping them understand the myth that car driving is some kind of entitlement without external costs on the rest of society, and in helping people be more thoughtful, could do a lot of good generally…
