Why is the Audi e-Tron's regenerative braking system beneficial?

I've heard that electric vehicles use a regenerative braking system to capture and convert energy that would otherwise be lost during braking. How does this help improve the driving experience of the Audi e-Tron?

The regenerative braking system in the Audi e-Tron works by converting the kinetic energy of the vehicle into electrical energy, which is then stored in the battery. This helps to improve efficiency and range, as the system reduces the amount of energy needed from the battery to power the vehicle.
