Paris being 5th when biking there is pure chaos compared to many Asian cities makes the ranking look capricious. Paris's City hall is definitely pro bike and a lot of money and effort was poured into infrastructure, but that dosn't suddenly makes it safe or largely adopted.
More generally, infrastructure isn't everything. Tokyo small streets with absolutely no markings can be way safer and bike friendlier than a bright lane in the middle of constant car traffic.
I'll note the company doing the ranking is based on Paris, so familiarity might hide many of the flaws.
I didn't even feel particularly safe as a pedestrian in Tokyo or Osaka. Despite the good public transport, Japanese cities have cars absolutely everywhere, even in tiny streets that should really be pedestrian zones. Paris is much better in my opinion.
Tokyo fundamentally doesn't define pedestrian only zones except in very specific conditions.
I get why you'd feel unsafe, but IMHO it's the exact opposite effect: 99% of the streets don't have a sidewalk or anything specific for pedestrian, and thus are pedestrian first.
Small kids, dogs, cats, elderlies will be walking in the middle of the street. As a result cars drive way slower than they'd do in Paris and they need to be way more alert to what's happening. Every small street is basically the same as the pedestrian zone in the middle of Paris.
Came here to say that. I've lived a long time in both Amsteram and Paris, and seeing those two cities close in that ranking call the whole thing into question. For sure, cities couldn't game the metrics used by tha ranking, but I'm sure the metrics definitions have been gamed to make some cities look better.
"Usage and Reach" is ranked better for Paris than Amsterdam? But in Amsterdam I can safely and efficiently bicycle from anywhere to anywhere, including across the rings, to the countryside and even to the sea, with the kids, and no fear. In Paris, I would not dare to venture outside of the touristic city center, and even there I would keep an eye on kids.
