Parking aids are software systems designed to make parking easier. They usually employ cameras (and send their feeds to the cockpit where they're viewable on the center display or the driver's display or both) and proximity sensors. The sensors can be mounted on the front and rear of the car, and our spec pages tell you where they can be found. We also let you know if a given EV model has reversing camera tech and any auto-parking software.
Keep in mind that these may be optional paid extras and not included in the base model of an EV.
