They all do better than this.

For moving parts most implementations use a Bob scaling algorithm with diagonal filtering, which produces results which are better than a Bob algorithm based on simple Bilinear scaling.

That sounds about right for motion adaptive deinterlacing but modern GPUs use vector adaptive deinterlacing, which is far better at reproducing the "original" full resolution progressive video than motion adaptive deinterlacing. Both the GTS250 and GT430 do some form of vector adaptive deinterlacing.
These examples are from the Cheese Slice test:
