Well in Netherlands we also do have cars similar to kei-cars called brommobielen (micro cars). Canta is a good example: https://en.wikipedia.org/wiki/Canta_(vehicle)

These things are allowed on some bike paths too.

In a way, maybe? Although weird small electric cycle/cars have been a thing for quite a while.

I have a similarly priced model, but from a different brand. Some of the extras are definitely debatable, but convenient. A second battery, belt drive, Rohloff electronic gear box. A chain with a derailleur definitely does the job, but belt and Rohloff need much less maintenance and I’m bad at maintaining chains. Second battery is useful since we actually do trips that go past 50 miles.

So even if both are not strictly needed, this bike replaces my car. And it’s pretty bad at social signaling, most people don’t realize what the ride costs.

These are for the times when someone says "I have to deliver some stuff N miles/km across town, why would I use a car?"

N is likely to be single digits, though not necessarily.

It's a somewhat similar rationale for why many big cities have bicycle couriers - it just makes more sense for a bunch of stuff to move it this way.

That doesn't mean that your 100 mile journey is also an obvious candidate for a bicycle (though it also doesn't mean that it isn't).

Almost no-one will make a 50 km trip with a cargo bike. But it's quite likely they don't own a costly and space-hogging car, but will rent one for the few times they need one.

(Note: 50 km is the equivalent of the 30 miles in parent's original comment.)

Note: GP edited up to 100km, then 100mile.

I do trips in that range for weekends and holidays. Kid loves sitting up front and 70-90km is definitely an achievable distance - about 5 hours of riding time.
