Great job on implementing the core functionalities and ensuring user authentication and authorization! 🎉 While there are a few minor issues related to production settings and URL configurations, they don't significantly impact the current functionality. Keep up the good work and consider addressing these minor points for future improvements. 😊

The ManufacturerListView is correctly using LoginRequiredMixin to ensure that only authenticated users can access this view.

In CarListView, the use of select_related is appropriate for optimizing database queries by fetching related manufacturer objects in the same query.

The condition to check if the driver is the current user is correctly implemented. This helps in highlighting the current user's entry in the list.

The link to the driver's detail page is correctly implemented using the driver-detail URL pattern. Ensure that the driver-detail view is correctly set up to handle this URL.

The template correctly appends '(Me)' to the current user's entry, which is a nice touch for user experience.

The use of the pluralize filter is correct and ensures proper grammar when displaying the number of visits. This enhances the user experience by dynamically adjusting the text based on the visit count.
