Just purchased a 2019 Niro Plug-In with a cargo net that I wrongly assumed would be a net that would stretch across the back of the trunk area (instead it just straps small items to the floor). Anyone come up with any way to keep groceries from falling over? Would want something that doesn't take up a lot of space when not in use. Possibly something that makes use of the anchor points built into the car. Loving everything else about the Niro.
