There are two pairs of railway crossing squiggle barriers on my commute. I fell on my butt twice in the same week trying to navigate them. Now I dismount and walk, like the sign next to the barriers tells me to.
No need to get defensive.
This has nothing to do with me, but you're comparing an obstacle with signs indicating to walk the bike to a section of MUP intended to accommodate bicycles, but poorly engineered.
That's not apples and oranges, it's
road apples and oranges.
