what’s the use of the cart that pushes back the airplane? Can planes not reverse without it?

Answer 1

They technically could using reverse thrust but it uses a lot of fuel, can suck in debris, damage the gate, and hard due to the pilots not being able to see the rear of the aircraft. It just makes more sense to have the ground crew do it
