I would like to suggest adding a wider variety of civilian vehicles to the game. In a post-apocalyptic world, it would make more sense to see vehicles that normal people used in everyday life, rather than mostly military-style vehicles.
Examples of vehicles that could fit well in the world:
Sedans – common city vehicles with balanced speed and storage.
Hatchbacks – smaller cars, faster but with limited storage.
Station wagons – great for carrying more loot.
Pickup trucks – very useful for transporting materials and resources.
Cargo vans – slower vehicles but with large storage capacity.
SUVs – good for traveling across rough terrain.
It could also be interesting to include some survivor-modified vehicles, such as:
Pickups with improvised metal protection
Vans with roof storage or extra cargo racks
Old vehicles reinforced with scrap metal
Some rarer vehicles could also add variety to the world, such as:
Ambulances
Motorhomes or campers
Old farm trucks
Light vehicles could also be interesting for survival gameplay:
Motorcycles for faster travel
Bicycles for quiet movement and low resource use
Adding more civilian vehicles would make the world feel more believable and immersive, since in an apocalypse most of the vehicles left behind would be the ones used by ordinary people.
