I read the answer for this post which says you can do something like this:
When viewing $wp_query everything seems to be working fine. That is, I'm getting 'car' post types that have the 'red' term assigned. However, the request uses the 'color' custom taxonomy template. (In my case this is taxonomy.php.)
