There is no way you'll get any equestrian to treat these horses like rabbits or even kangaroos as a pest. We're a capture and train because they're beautiful while helping the forests from going up. British aren't going to give our horses back.
They're not dogs, it's called breaking in for a reason. Horses respond to emotion/body language so if you get comfortable with even a feral/unbroken horse you'll find a way.
Maybe it depends on what country your in and the DNA in the horses, if they came from highly domesticated stock. Me and a mate broke in 2 Australian Brumbies when I was 16 years old using the English break in method, you basically care for the horse cleaning feeding walking lunging then riding etc they were fine ran up to people at the fence no problem.
