Funny that it's so noticeable because of the hostile architecture.

What hostile architecture? This is on the underground. Nobody is going to be sleeping on these seats.

The hostile architecture in this instance is the choice to use benches instead of seats with back support.

What is hostile about the architecture here? The armrests?

If the (quite useless) armrests weren't there to prevent the homeless from sleeping on them, people wouldn't be sitting in the exact same spot every time, causing a light smear instead of defined person-like shaped on the wall.
