A friend got into it around 8th year of school and strung me along so I can still read it pretty comfortably, but without that, the answer would be no - some of the most common letters, like 'e', are just too different.

I get the sense, though, that especially in Bavaria it held on for a while even after WWII - very rarely you still see storefront signs written in it for flair, and somewhat more often you encounter subtle "Sütterlinisms" like having a lower half-arc above the cursive letter 'u' in the handwriting of older people and signage meant to evoke it.
