Rural delivery has always been private vehicles. Carriers with spouses who have good jobs buy right hand drive Subaru’s. Everyone else drives some hooptie mobile.

A lot of farm spouses used to do this gig. A moderately reliable car and a mechanically inclination is a key to success — cars need brakes every 3-6 weeks.

USPS in general started buying more low bidder commercial vehicles because their package volumes have increased and the bespoke, cheap mail trucks were too small.
