What is the average hourly rate for automotive workers based on a 40 hour work week?

This is very hard to answer. If you have no experience $9per hr experienced techs make $15 up to $25. Although if you are a flat rate tech making $15 per hr, you can bill 20 to 100 hrs a week in a 40hr week. So you will make 15 x 20 or 15x100 it depends how good of a tech you are.
