I love the idea of buggies used for traversal. I want to flesh traveling just a little bit more with a suggestion that doesnt rely on buggies or ziplines.
SUGGESTION: I think its safe to assume that alot of players in Grounded came from gamepass so i'd like to turn our attention to another phenomenal gamepass game: Jusant. Jusant had an incredible climbing mechanic based around stamina management and the amount of pins the player that could be upgraded. I think Grounded should adopt a similar climbing mechanic. Have the players be able to climb vertical walls, stems, incline rocks, pots, etc. Using their hands and stamina. This would obviously be limited by distance and stamina drained. However, if we can take some bug parts and make either a special bug armor or climbing equipment we could expand the distance and enhance stamina drain during climbs. I feel like climbing can open up the design of some environments and also make traversal more rewarding. We could even have special items tucked away nocks and crannies that can only be found by climbing. I think having different options for traversal is good to cater to different kinds of players.
