Here is Marine Drive in Vancouver: https://maps.app.goo.gl/ThnKn7PmD8sKSnNs5
Speed limit 50km/h ... It has lights and intersections. Almost no pedestrians.
Vancouver has many wide multi-lane streets. Some in denser areas with more pedestrian traffic some less. It has almost no real highways going to the city.
Agreed that it makes no sense to restrict that kind of road to 30km/h, but to be fair most cities that have moved to 30km/h would have excluded that road. Even Amsterdam left the main throughfares at 50km/h: https://www.amsterdam.nl/30-km-u-in-de-stad/
