The issue is here is that fatigue effects us all differently and minor changes in circumstance can make every situation unique. Sometimes I arrive from a 13 hour flight perfectly fine, other times using the same flight I arrive and wouldn't feel safe driving, particularly on unfamiliar roads.
I think with any situation like that you have to be sensible and honest with yourself; if you arrive and don't feel fit to drive, than check in to the nearest hotel/motel and swallow the cost as an investment in your life/health/safety. If you feel fit, then carry on and take the 160km drive with caution.
