I can see the points about bridge strikes, and I agree that it shouldn’t happen.
I also have to question the motives behind posting them on the internet.
Is the poster doing it to help others, or just emulating the schoolboy who revelled in the schadenfreude of somebody tripping over and “laughing” in an exaggerated fashion?
We all knew one or more of those, and nobody except their sad-case, special-subjects hangers-on had any time for them.
Do you recognise yourself in either of these people?
