When I need to sit behind my SUV/car I have a folding chair.
But so many crap designs by so many manufacturers become myths and must have - a rear wiper without a washer in the 911s since time immemorial and I could go on listing them. Just because it's always been there (like a gauge cluster you can't see the outer ones) doesn't make it either practical or useful.
As for the wrong tool, I wasn't able to find a car that would work by 50 below, haul 5 siberians etc. as VDub in their infinite stupidity priced the Touareg out of the ballpark, hasn't sold it in the US for years and nothing else fit the bill. Sorry if the absolute impracticability of this contraption offends purists.
Oh and FWIW, the 928 was years ahead of its time though not really a 911 (neither was the 912, not the 924 or the 944 or the 968 ...); heck it wasn't AIR COOLED; way before emission standards and hp forced Porsche to abandon the system
