All hail the robot cab overlords. An autonomous taxi program was already being tested, but now Delphi Automotive says it’ll dispatch a few self-driving vehicles to ferry people to hard-to-access Singaporean mass transit hubs. With a program already under way in Silicon Valley, the British vehicle electronics supplier is expected to roll out new American and European pilots this year. Initially, Singapore’s six robot jitneys will follow three preset routes — and have a human driver as a safety measure. If that works, by 2019 they’ll branch out on their own.
