Took a moment to think about this, and I think it would be pretty cool to have a fallout game set in an absolutely humongously large map and have a system where you can fast travel small distances to essentially repair shop settlements in a vehicle that was possibly repaired and upgraded to use things like fusion cores or something else lore friendly enough. But if you wanna go from one side of the map to the other, you gotta drive closer to other settlements to try and keep some semblance of balance, possibly, to make the vehicle feel more worthwhile.

Just a fun little vehicle that has properties similar to a companion outside of hardcore/survival/whatever mode, but instead of going unconscious and eventually getting back up, you repair it with parts you find scattered all around the map or have purchased from various vendors. If it gets damaged, up until a certain amount, you could be able to fast travel to the nearest repair shop type area you’ve unlocked and you could repair it.

Wanna run into low level raiders? Go for it! Just watch out for the guy with a rocket launcher whose job is to try and blow up your vehicle and you! Wanna jump off a cliff and survive? Ramp it! Want a motorcycle instead of a car? You purchase that instead of a car. Car gives more protection whereas the motorcycle goes faster, but gives less protection to your character.

Just things to make the game feel more chaotic. Though I could see why people would not want anything like this, it sounds fun to me as a fan of digital vehicular antics. As for the logistics of making all that work, I couldn’t tell you. Sounds like a nightmare due to how a lot of areas like settlements feel like they’re made in such a way that vehicles would be hard to implement.
