Nothing to do with sensation.

If VFR you are supposed to be looking out the window, not staring at
the instruments, so the sensation of an uncoordinated turn would
normally be the first indication it is happening.

In VFR, if you aren't looking out the window or at your instruments, sensation
won't help you.
