Well, most of Europe is south of Norway, and there's a lot of comparable cycling culture and facilities there.
Unless you mean south of the equator, like here in Australia, but unfortunately we're not so good with that. I can't speak to much of the rest of the south (of the equator) unfortunately.
As someone that has enjoyed Minneapolis St Pauls heavily interconnected bike path system, and then goes to uber-car-centric southern areas (not even shoulders on the roads to support bikes), it blows my mind, especially some place like Houston.
You don't even have "real winter"! It is far easier on a bike dealing with rain than dealing with six inches of snow and packed ice. Four seasons of bike trips! Don't they know what they are missing?
And with e-bikes and the like, you don't even need to worry about getting sweaty in the 100 degree heat. Instead it is an awesome breezy trip.
Houston for example has the beginnings of this: a big path down some stream/water transport that splits down the middle of the city (Macgregor or something like it. A built in ebike crosscity-thoroughfare, you just need to urban plan some extension bike lanes and boom the city is 10x more bikeable.
But Houston is, for example, forbidden by the Texas legislature from funding any mass transportation, because the Texas GOP is ... insane. Well, everything in Texas is insane.
