On Monday, Audi announced that next month in Munich it will be teaming up with Amazon and German logistics company DHL to run a pilot program to make parcel deliveries to an Audi owner's car trunk. The idea behind the program is that if a delivery person tries to leave a package at a person's home, there's a good chance the recipient won't be there and the package will have to go back to the processing facility. If the delivery person tries to take a package to a person's car, he or she can use keyless access to that trunk to leave it there securely.

Theoretically, the way it works is this: an Audi owner orders a package and gets a specific delivery time frame from Amazon. The car owner then gives an approximate location for the car during the delivery window and agrees to let the Audi be tracked during that specific time frame. The DHL delivery person receives a digital code to access the trunk of that vehicle, which Audi says “can be used one time only for a specific period of time and expires as soon as the luggage compartment has been closed again.” The DHL delivery person finds the car, opens the trunk, puts the parcel in the trunk, and then can't open the trunk again.

The pilot program is only open to people who live in Munich, have Audis, and are Amazon Prime members, so the target demographic is very small. If you're lucky enough to answer yes to all three of those qualifications, just make sure you don't order a sweet, delicious gallon of Tuscan Whole Milk. Unless you also order a sick cooler to keep your milk nice and cold, too.

Audi, Amazon, and DHL's effort is just the latest in a number of attempts to bring new ideas to logistics problems—in 2012, Amazon started setting up lockers in stores and public areas that users could have their goods delivered to instead of having failed delivery attempts at home. Last September, DHL launched a program to deliver medicine to a remote island off the north coast of Germany via a drone called the “parcelcopter.”
