I realised it minutes after posting it when I noticed the driving was on the left (as opposed to right in NL) :-). The architecture is very close to those in the NL though which fooled my lazy eyes. Pedestrian islands, enabling free movement of cyclists with clear markings etc.,
The usual cooperative approach of "I have right of way, I can help my peer by accelerating a bit so they don't have to wait so long" seems to only work with participants in roughly the same weight class.
Recently, local governments are moving away from the real small roundabouts like this one because in the dark, when it is raining, with cyclists who are without lights, these are still somewhat unsafe: https://www.telegraaf.nl/images/1540x866/filters:format(jpeg...
These are much more modern, and car drivers can more easily see cyclists and mopeds come: https://www.denhaag.nl/upload/0690e94f-f7ac-43a3-8c1e-4fb768...
Oh, and yes, car drivers can sometimes be aggressive. The same counts for cyclists though. I guess both kinds of people are just like normal people. And by the way, a lot of people are one day car drivers, the next day cyclist, there is a lot of sympathy.
(yes, the answer will be "but children!", but I'm a believer in "treat cyclists like children and only children will ride bikes!" and I'd be a firm believer if the Netherlands didn't have this annoying habit of proving me wrong ;))
With a segregated bike lane the driver turbing right has the bike lane in front of them.
I suppose there's a better way. However, as a society, Dutch have decided to go whole nine yards to being a cycling friendly nation. And it shows and has its benefits.
