General Motors is significantly expanding the reach of its “Super Cruise” semi-automated driving system, incorporating approximately 350,000 miles (563,000 kilometers) of roadways in the U.S. and Canada. This expansion nearly doubles the system’s coverage, encompassing a variety of road types, including limited-access divided highways and two-lane roads connecting cities and towns. Unlike some competing systems, GM asserts that Super Cruise is ready to navigate roads with intersections and crossing traffic, offering drivers an advanced level of assistance.
Super Cruise allows drivers to momentarily take their hands off the steering wheel, but they must remain vigilant and be prepared to intervene when needed, as the system does not enable fully autonomous driving. In contrast to other driver-assist systems, Super Cruise employs both radar and camera sensors to detect obstacles, providing additional layers of safety and responsiveness.
Kelly Funkhouser, associate director of vehicle technology at Consumer Reports’ auto test center, commends Super Cruise for its robust driver-monitoring system, which utilizes an infrared camera to ensure the driver’s attention is focused on the road. However, concerns are raised about the potential risks associated with allowing hands-off steering on two-lane roads, where reaction time could be delayed, and distractions may pose a challenge.
The gradual expansion, facilitated through online software updates at no additional cost, is a strategic move by GM to enhance Super Cruise’s capabilities. The expansion is expected to unfold progressively throughout the coming year, reflecting GM’s commitment to advancing the accessibility and effectiveness of semi-automated driving technologies.
