Corduroy paving used instead of textured

The new shared-use path here is lovely except they've installed corduroy paving, with the very narrow bumps, on the newest stretch, to indicate the cycling and pedestrian halves, instead of the usual fat textured paving. Last week in the bad weather it caught my wheel and I skidded on it, only just avoided coming off completely. I couldn't get a photo because it was after dark, but you know the paving I mean. It's not suitable for cycle paths under any circumstances and I don't know why they've used it here. The section they installed previously, along Gregory Park up to the back entrance of the P&R, has the correct paving.
