How do you craft vehicles in Fallen Earth?

The crafting of vehicles is governed by two primary Tradeskills: Nature provides access to horses, as well as feed recipes and Veterinary Kits. Science is used for all other vehicle types. Obtaining recipes for vehicles does require going through several missions. Once you have those initial ATV recipes, you can develop the abilities needed to make all the other types of vehicles. The Science Tradeskill also allows you to craft various kinds of fuel (gasoline, biodiesel, batteries) and Repair Kits. Vehicles can be damaged through use, as well as in attacks carried out by NPCs or PCs in PvP zones.
