Car makers such as Mercedes and General Motors Co  as well as technology giants like Google Inc
and Apple Inc are already developing driverless vehicles which can complete whole journeys without human input.

But some analysts expect self-driving cars will not appear on global markets until the early- or mid-2020s, partly due to regulatory hurdles.

Hyundai Motor, like other automakers, already has autonomous features in premium vehicles like the Genesis, which can be programmed to hit the brakes when a pedestrian steps out.
