Toyota revealed a self-driving concept vehicle, the e-Palette, at the International Consumer Electronics Show (CES) in Las Vegas on Monday.

The electric, box-shaped vehicle will come in three sizes. The largest will be around the size of a bus and be able to haul freight and make large deliveries, while the smallest will be compact enough to travel on sidewalks. Toyota envisions the e-Palette will serve a variety of potential uses, allowing businesses to deliver goods, transport people, or use the vehicle as a mobile storefront or office.
