categories - why category__and and category__in wont work togather?

I am having an issue here. I want to get all the post that are related to the current post at the same time it will also have a common category term.

for example:

Post XYZ has categories car, Truck, and Bus.

So i want to get any posts that have car or truck or bus at the same time it will also have category "Toronto"

What would be the query?

You need a query like this -

$args = array(
    'post_type' => 'post',
    'tax_query' => array(
        'relation' => 'AND',
        array(
            'taxonomy' => 'category',
            'field' => 'slug',
            'terms' => array( 'car', 'truck', 'bus' ),
            'operator' => 'IN'
        ),
        array(
            'taxonomy' => 'category',
            'field' => 'name',
            'terms' => 'Toronto'
        )
    )
);
