When you are good at it, no, it does not take a wide road (or driveway) to back a trailer. But, it takes practice.
Start with a straight alignment of trailer and tow vehicle. Back across three rows of parking spaces (you are practicing in an empty parking lot, remember). Keep it straight. Notice how little you move your steering wheel.
Then, start straight, then back to the second parking space to your left, then right, two rows back. The point is, do small angles, then a little larger angles, before you try sharp angles. Get used to the small movements needed to turn.
Good luck!
