Kroger announced plans Thursday to partner with driverless car company Nuro to deliver groceries using its autonomous vehicles.

The partnership comes as the U.S.'s largest grocery players continue to tackle the expensive challenge of "last mile delivery" — the final step in getting a product to a shopper's home. It is a feat that is particularly perilous when dealing with fragile products like fresh food. It is further complicated by populations that vary wildly across the U.S, with some far less dense that others.
