Problem with both the Gunter 2 AND the Hatchback in this patch.
- There is no HUD indicator showing the option to "get in" or for refueling the gas tanks. However, if you look at the right spots and hold F it will let you get in or refuel.
- Once you get into either vehicle, you cannot get out, and no HUD indicator appears as well.
So at least with my tests in offline mode (using community offline mode, no other mods, and completely new DayZ settings folder), once you get into a vehicle, you are unable to get out.
