Southeast Asian ride-hailing service Grab disclosed on Monday that Japan's Honda Motor Co had invested in the firm, as part of a $750 million funding announced previously, to collaborate on motorbike-hailing services. This is the latest tie-up of its kind in the auto industry, where carmakers such as Volkswagen , Toyota Motor Corp and General Motors have also struck deals with ride-sharing firms to hedge against a shift in the vehicle market away from private ownership. Grab, the biggest rival to ride-sharing service Uber Technologies Inc [UBER.UL] in Southeast Asia, said Honda had agreed to invest an undisclosed amount in the firm, and the two would form a partnership to develop the ride-sharing technology and related driver education programs.
