But that is accurate, given the default file we search for on test_driver_data.c
is test-driver_data.bin. It also does not create a conflict to overwrite a file
used on driver_data.sh as driver_data.sh uses a custom path. I think the note
above on custom path is sufficient for the developer or user to be aware of
the fact the driver_data.sh does it own thing, and that the example is just a
manual test case.

What do you mean by that its incorrect ?
