*BC note - this breaks code if people build on top of the incorrect returned value `drife`.

Fixes the `singular` for `drives`. I've added more test values to prove more edge cases and to show this changes doesn't break other `singular`-look ups.
In the test class i've added a few `known issues` for later reference/fixure.
