Ford and Uber-competitor Lyft said they will team up to develop self-driving vehicles for the US-based Lyft ride-hailing service. The two companies plan to design software that lets Ford vehicles communicate with Lyft’s app-based services.

Lyft has struck a series of partnerships with companies developing the technology, including Waymo, the self-driving car unit of Alphabet, Tata Motors’ Jaguar Land Rover and start-ups Drive.ai and NuTonomy.

It is also forming its own autonomous-car development division, to be staffed by hundreds of engineers and technicians in Palo Alto.

Lyft also has a partnership with General Motors, which has invested about US$500 million in the company and added a board member. Last year, GM said it planned to work with Lyft to put more self-driving taxis on US roads sometime this year, using technology acquired from start-up Cruise Automation in a $1 billion deal.
