Horseriders are at a unique advantage when learning to drive.
Not only can they see further ahead in the road but they’re up above much danger (which people on two wheels aren’t). And they’ll have learned how to behave on the road, plus much of what to expect.
But they’re still more vulnerable. The flight-animal they’re sitting on has senses / emotions and is easily spooked.
Your control of the car needs asymmetric use of hands and feet, as with a horse. (You can even talk to it ... but what you say won’t change what your machine does). A car’s gears can be likened to a horse changing between walking, trotting, cantering, and galloping as it gathers speed.
Get set properly before you go. Keep the reins close (limbs close to pedals and wheel) so you can effect a quick change of speed or direction. Look around you (and listen) before you ask “your charge” to change where it’s going, and how fast.
