Context is the king. Read the original comment I'was replying. As for Amsterdam - it's a tiny city area wise, 30 km/h is mostly core. All highway limits stays the same. Map they provided show 50 km/h outside of the very centre. I'm glad for them if that make a difference. As a side note I didn't enjoy Amsterdam public transport (again comparing with Montreal). As a related fact in Montreal that stretch of the road https://maps.app.goo.gl/dgG8avYABUgbZ7BTA https://maps.app.goo.gl/dgG8avYABUgbZ7BTA was switched from 50km/h to 40km/h. As you can see it has fences on both sides, so it's hard to justify safety reasons here.
