I'm being serious.

Every place I lived in Stockholm had outdoor bike bike parking that was covered. I don't see the problem.

In Frankfurt, it's not covered but it doesn't really snow that much here.

I don't know anyone who would bring their city bike inside. No one will steal them as they have little aftermarket value. What someone will do is ride away on them, that's why they have a wheel lock. Outside any city supermarket there would be a dozen unchained but wheel-locked bikes on the sidewalk (kickstand is very handy here) outside the entrance/exit.

The front basket on my Monark (steel covered with rubber) could lift off the handlebars and brought inside the store to use as a shopping carry to collect groceries (it actually looked like an old shopping carry), I could go to check-out with it, and run my purchase through the register and drop them back in the basket leave the store, put it over the handlebars, ride home, leave the bike outside in covered parking, and carry the groceries upstairs with zero hassles and not even require a bag.

Let's see the Via 3 do that then I'll even acknowledge it's existence.
