Is rclone sync target fully usable as a regular filesystem without rclone?

This is probably the most basic question that could be asked. But surprisingly, the answer doesn't seem obvious, even to forum and web search. Isn't answered in a clear way in the docs.

If I run rclone sync, will the target contain a "regular", browseable, readable mirror of the source folder and file structure? (Filters notwithstanding?) In other words, can I browse, open files, on the target computer, just as anyone normally would, without needing to run rclone mount? (I intend to treat the target as read-only, if that matters.)

Or if not by default, are there any options to make it do that?

In other words, are the results something like rsync -av would accomplish.
