San Francisco is being used as a test track for driverless vehicles

Welcome to the streets of San Francisco, where the world's biggest experiment in self-driving 'robotaxis' is under way. One local told me: 'The self-driving future has arrived on the streets of San Francisco and it's a nightmare. Unlike San Francisco, where robotaxis have no one inside, the Scottish buses will have a 'safety driver' ready to grab the controls in an emergency. As we operate in some of the densest parts of San Francisco, we interact with active emergency vehicles day and night. 'We are concerned that if autonomous vehicles are allowed limitless, driverless operations in San Francisco, that traffic impacts grow exponentially.
