People say the same thing about winter in the Northeast. Then when they see how convenient and freeing it is to ride a bike, they quickly learn to deal with the weather.
If you're claiming that they won't, I'll happily be your counterexample. Buying a Brompton and riding 3 miles from the end of public transit to work through pretty much all weather in Boston was about the best thing I did for my sanity in all of 2019. Yes, on the snowy and icy days too.
I did a fair amount of bike commuting in Cleveland as well, though the drive was less hellish and I drove some of the lousier days.
The worst part of moving to Vermont, perversely, is that I get less exercise because it's a 25 mile one-way trip to the shop I work out of.
I mean, no offense, of course some people like you will bike in all weather, but the reality is that a lot of people will not. See this study, and that's for the Netherlands, not NA winter.
I know a lot of people that ride their bikes at work at such temperatures, and one of the biggest issues with doing that isn't the cold - exertion really warms you up - but badly maintained, snowy shoulders and a higher risk of cars crashing into you.
I'm not sure how to convince someone that people stop going outside when the weather sucks. But hey, you've got a New York Times article, so that obviously means my eyes are wrong, right?
I don't know how to convince someone that people stop going outside when the weather gets cold. I thought that was a normal fact of life for everyone who doesn't have an outdoor job.
