But that's exactly what visual-line-mode is about: it treats every
_screen_ line as if it were a physical line.  IOW, this cursor motion
is a major, perhaps the main, feature of visual-line-mode.  That's how
other applications behave, and that's why most users like
visual-line-mode.

As for the cursor not jumping to the end of line: Emacs cannot put the
cursor where there's no text.  This is a basic design of the cursor
display in Emacs.  The only exception I know of is picture-mode, and
that only happens there because AFAIR Emacs adds spaces to prolong the
line to the cursor position.
