I guess an interest in trucks and great expanses of open country help, inversely we here all know and love a little hatchback and have roads leading to almost every square kilometre on the continent. However, there's nothing in these videos that doesn't look it'll stump a Rally1, so what makes it off-roading? They are all following the same course which is worn like something from Kenya or Sardinia.
An FIA system Baja will be a rally, but the one that gave them the name, the Baja 1000, is a race not a rally, and SCORE is not a FIA member associate.
