I mean you're not wrong but you're not refuting that bike's are less comfortable, just that our lives would be better off with a little less comfort. I agree with you, but I don't think most people would.
I'm not trying to. My point is that there is no absolute scale of comfort. We are comfortable with what we are used to. That's why one person's comfort zone is different to another's. When I started to drive seriously it was way less comfortable than cycling for me. Manoeuvring a four-wheeled vehicle around is considerably more difficult. Acceleration is pitiful and you can't stop easily. You have to actually queue behind other cars in heavy traffic! Trapped in the little box in which you must remain, even if walking is now quicker. And just look at how angry it makes people. I've seen people literally go mad stuck in traffic. They're all on edge and the slightest mistake or unexpected behaviour can turn them into a frenzy. And this is meant to be the pinnacle of comfort! Because I don't get wet when there's a little rain?!
