Self-driving Chevrolet Bolt EV taxis could be on American roads within a year. General Motors and ride service Lyft will begin testing self-driving technology developed by Cruise Automation Inc., which GM plans to buy for $1 billion. GM declined to confirm the report in the Wall Street Journal, but did say it ‘continues to make progress’ on its goal to build an ‘integrated on-demand autonomous network’ with Lyft, in which it invested $500 million in January. ‘Similarly, we have said the Bolt is the ideal platform for ride-sharing solutions . . . we believe electrification blends perfectly with autonomy when it comes to technology integration.’ A host city for the tests was not disclosed.
