It's not intended as a serious off-roader .... think the old long distance rallies of yesteryear (London to Sydney Marathon etc) or stage rally AH 3000s .... more for off the beaten track dirt roads in Morroco or desert tracks around Escalante than 'rock-crawling' in Moab or mud-plugging in Tenessee!
Two wheel drives can go surprising places (I've taken a 2CV out into the Sahara and an Austin A40 over horse tracks in the mountains of Southern Yugoslavia back when it was still Yugoslavia) .... .. and the one in the promotional vid has already seen more rough-stuff than 90% of the new Land Rover Defenders sold ever will.
Remains to be seen if any of the 8 purchasers will be minded to put them to the test ... if they do (and they're decent drivers) they may be surprised the places they get! 🙂
