Grids are problematic because one can observe you at the boundaries, moving from one cell to another, so there are moments when you are very accurately localizable.

Ah yes good point (you'd be briefly localizable to a line), you'd need to add some hysteresis and delay for dynamical targets.

So something like

shown_pos(t) = mode(quantize(pos(t-j)),...,quantize(pos(t-j-k)))

For some delay j and hysteresis k.
