CGMZ Vehicle Interiors (Patreon)

This plugin allows you to press a button and enter the interior of a vehicle (really just another map of your choosing). This makes it seem like the player can go in/out of their vehicles instead of just driving the vehicle around the map. You can also force the player to enter/exit a vehicle by event command if needed (for things like cutscenes that involve entering/exiting a vehicle).

Update 11/19: Added button for touch UI to enter a vehicle
