Walmart and Ford have begun working together on a joint program that will explore how the two companies can utilize self-driving cars.

According to reports, the project was announced by Ford and has begun in the Miami area, where the automaker has begun building an autonomous vehicle business expected to launch in 2021.  The joint venture between the two companies will focus on how self-driving vehicles could be used to deliver groceries and other products.  Research will focus on which vehicle configurations will work best and which products would be most easily deliverable.

Ford has been performing tests with their autonomous vehicles in Miami since February.  Walmart has also been working with self-driving cars, as they partnered with a Phoenix area company called Waymo on a similar grocery delivery program.
