On Wednesday, Honda Motor Co Ltd said it would invest $2.75 billion (£2.13 billion) and take a 5.7 percent stake in General Motors Co's Cruise self-driving vehicle unit, in which SoftBank is also an investor. At the Paris Auto Show on Wednesday, the heads of Daimler AG and Renault said the two companies may expand their cooperation to batteries, self-driving vehicles and mobility services. Toyota and SoftBank do not have any major partnerships in mobility technologies at the moment, although both are developing technologies for self-driving vehicles, car sharing and other services. Toyota, one of the world's largest automakers, has been developing automated driving and artificial intelligence technologies in-house and with its group suppliers, while acquiring some technology start-ups. Both Toyota and SoftBank have investments and partnerships with Uber Technologies and ride-hailing firm Grab, and Didi Chuxing.
