I hear where you’re coming from but this isn’t what the article said. Dutch people use other modes of transportation than bikes. Just not as much. There are use cases where cars are hard to replace but right now, we are using them for way too many things. Public transportation is another alternative to cars that is way to often overlooked.

The practicality isn’t questionable.

Of course there are outliers and places/people it wouldn’t work for but the vast majority should be absolutely fine.

I think this shouldn’t be read as an individual call to action as in ‘everyone has to do their part and start cycling’.
Rather, it should be a call for governments to support a changing traffic and transportation infrastructure.

It’s a chicken and egg problem, unfortunately. Cities won’t improve conditions for cyclists if they only see car traffic and people will avoid cycling under bad conditions.

My Hometown here in Germany lost out on about 3 Millions of funding for bike infrastructure in the last decade, because no one in the city government felt responsible to plan any infrastructure in the transportation department.
