I've never driven a horse, let alone taught one how to drive, but I can say this: UR DOIN IT WRONG.
What is the thought process of "trainers" like these?
"Let's confuse our hot, green horse by having two people whip him around in a circle, and then we'll hook him up to a twelve-foot cart! That'll teach him how to drive! Don't forget the misfitting tack that keeps falling off or slipping! Hell, bring the whole crew out to the barn and we'll chase him around and hit him in the face and pull on his mouth! We'll watch him fall over, get tangled up, buck and rear, bolt, and everything else! PAR-TAY!"
People just baffle me. These idiots could probably screw up with asking a well-schooled horse to walk.
There's a method known as longe-lining, contraptions called training buggies, attributes like patience and good horsemanship, and an apparently dying wisdom called common sense.
A disgrace to equestrianism, to driving, and to Poland all in one video.
