As mentioned upthread, for reasons of tight space and twisty track, I
think it highly unlikely that any LU tube stock will have
walk-through inter-car connections. After all, just think how
narrow and low the doorways would have to be!

Doesn't seem to be a problem for people in bendy buses when they go
around corners.

But bendies are wider, higher and much squarer than tube stock, so the
opening is far larger. Also, as articulated vehicles, the two halves
don't move much relative to each other, unlike non-articulated
carriages -- just look how much the adjacent carriage moves up and down
when a tube train is bouncing along.
