I used to bike to work every day. A lot of the time I would get there pretty sweaty.

This was when I was younger, in better shape, and when my health problems weren't giving me as much trouble. The last several times I got on a bike it was painful and exhausting. If I tried to commute somewhere today I'd probably collapse mid-way there with an asthma attack. If I did have a bike trailer, I wouldn't have anywhere to put it. I live in an apartment building with no elevator and nowhere to park or store anything on the ground level.

Everyone isn't in the same circumstances as you. That's the point.

But you go ahead and tell yourself whatever you want.

I had a co worker that daily drove a jeep on 37 inch tires, maybe 8 mpg. He lived like across town, not walkable but bikable for sure. He got one then lectric e bikes for like 800 bucks he said in the first 2 months of riding that to work every day he was in better shape and it had already paid for itself. Granted once winter came he was back to the jeep, but the fact that he spent almost a grand on a bike and it paid itself in less than a summer is pretty telling!
