It looks like Amazon isn’t the only technology company looking to step up its logistics game. Google was awarded a new patent on Tuesday that suggests the company is interested in developing its own autonomous delivery trucks. We already knew that Google is interested in creating a self-flying delivery drone system, but creating a fleet of self-driving delivery trucks is something much more ambitious, not to mention difficult. However, whereas Amazon has an obvious reason for wanting to step up its logistics game, none of Google’s services directly benefit autonomous delivery drones and trucks, so it’s not clear why the company is so interested in the technology, unless it just wants to diversify.
