As quickly as self-driving car technology is improving, it's still near-useless off-road. What good is an autonomous SUV if it can't drive to your camping site? Jaguar Land Rover hopes to fix that. It's showing off research into all-terrain self-driving tech that would adapt to different surfaces. A mix of cameras, lidar, radar and ultrasonic sound would give vehicles a sense of what they're driving on, and adapt accordingly -- say, going slow and steady on a dirt road. They would plot 3D paths that account for not just the ground, but low-hanging tree branches and other obstacles that could wreck your ride. You might not risk getting stuck in the mud simply because you didn't know how to tackle a challenging ravine.
