 I created new post category 'cars'. But cars are added/deleted via Php
 code automatically via:
 wp_insert_post(...)
 and
 wp_delete_post(...)

 So I wanted to remove 'add new car' from navigation menu. And somehow
 remove the 'delete' capability.

 So I used this code in plugins register_post_type $args:


 {{{
 array(
 ...
                 'capability_type'     => 'car',
                 /*'capabilities' => array(
                         'create_posts' => false, // Removes support for
 the "Add New" function - DOESN'T WORK
                         'delete_post' => false,
                         'publish_posts' => false,
                 ),
                 'map_meta_cap' => true, // Set to false, if users are not
 allowed to edit/delete existing posts
                 */
 ...)
 }}}

 Appears the 'add_new' is not shown, but now I got bunch of warnings all
 over the admin:
