Brief explanation

The previous code allows you to add interiors to vehicles not supported by the base mod; remove vehicles; or change their base interior type. In addition, the final block allows you to create a new interior type and assign it to any vehicles you want (both those supported and not supported by the mod).
The file with the code should be placed in media\lua\shared

Guide in development

You must use any cell with values ​​greater than (82,41), because that is the interior detection range.

In this example I'm going to use the cell (83,42)
