Reversing literally isn’t harder than driving forward.
Of course it is. Don’t be dense. Going forward there’s a huge windshield for you to look through with both eyes so your binocular vision gives you full depth perception. You’re moving in the direction you’re facing. The wheels that can’t be steered follow the wheels that can so you don’t need to think about them because they’ll always just follow.
Compare that with reversing where you’re facing forward but moving backward. You can only get a small, incomplete picture of where you’re heading using either small mirrors or a low-resolution camera. You can try to rotate in your seat if you have a useful back window, but even if you do it’s far away and so most of your view to the rear is going to be blocked by the car’s interior. In addition, you’re pushing the non-steered wheels with wheels that are steered, so that small movements of the steered wheels are amplified, so you have to be much more careful about where you’re pushing them.
There’s no question that driving backwards is harder than driving forwards.
