Vehicles are found randomly generated in nearly every world you visit. To earn them and recall/summon them at your will, you must first mount the vehicle and discover it in order to get them to your library. Additionally, most of these vehicles must be unlocked further by purchasing them with studs in your “discovery” library. After purchase, these vehicles can then be limitless-ly spawned, anytime and anywhere you want them.
Aside from how awesome these vehicles look, some of them even provide additional abilities or can even attack using their own ammunitions (missiles or lasers). Depending on the type of vehicle that you are using too, they can get you from one place to another a whole lot faster (especially when compared to simply walking).
