I never said anything negative about cargo bikes besides that they're not practical in the majority of cities in this car-dependent country.

I know Canada better than the vast majority of Canadians, I assure you; even if just because so many of them refuse to be critical about their way of life. Where are you that you're seeing these regularly? I know for certain I've seen more cybertrucks than cargo bikes (one) in the past few years living in three cities in Southern Ontario; never saw them out east. I've been all over this country, and I can name maybe five cities where -- given you can afford rent in the more densely populated, typically higher-income neighborhoods -- you could make this work given you also have much more time in a day than many workers are afforded.
