Sadly, you won't see Nuro's custom R1 vehicle (above) roll up to your home in the earliest stages of the pilot -- it'll be a modified Toyota Prius instead, and the very first phase will include a just-in-case driver. The purpose-built machines will only start delivering your goods sometime in the fall, after they've completed certification and testing.

This isn't the first self-driving grocery test in the state, as Waymo and Walmart are trialing pick-ups in Phoenix. This is, however, the first real chance many will have for driverless delivery. Just don't expect to see this service spread far and wide for a while. Autonomous car companies have gravitated toward Arizona both due to its support for truly driverless testing as well as its warm climate and relatively sparse population. You won't see mass adoption until completely driverless cars are both legal in more states and know how to handle snow, ultra-dense traffic and similar hazards.
