For context, this is the place they’re testing the 20km/h speed limit at. There’s no reasonable explanation to go faster than 20 km/h there anyway, regardless of legal limits.
It looks like there’s basically a longer bikeway that travels through a particularly built-up area there. The bikeway on either side of the housing area has more space on each side of the bikeway before reaching a building, so I’d expect bicyclists to use it as something of a highway, but there’s no great way to route around the houses here.
There’s a rail line on one side, but the other direction, there’s a vaguely-parallel bikeway maybe four blocks over, so some people can probably use that.

That’s rather important context.
The problem would then only be if they take a test made in a specific place with narrow paths and much traffic and apply it to all bikes everywhere.
