Sam joins Leo to talk about HD Maps and how they triangulate your position with not just satellites, but also maps generated from radar and lidar in your car. Accuracy is to the centimetre that way. It's the future of navigation. Mobile Eye is one such company that is working to put HD Maps in cars. Nissan's ProPilot will also have it this fall. Cars are also going to be getting ground penetrating radar to add to the accuracy to the navigation by identifying the location of what's underground as well. All that data is collated and adds to HD Maps.
