Autonomous cars are no longer science fiction. Despite growing hype, there's a lot of misunderstanding about them. The video aims to explain how self-driving cars work and how they will change the future of transportation, addressing common fears.
Self-driving capabilities are rated on a scale of zero to five. Level zero means full human control. Level one includes basic assists like cruise control. Level two involves simultaneous automated functions but still requires human supervision. Level three allows the car to manage critical functions under certain conditions, with the driver ready to take over. Level four is fully autonomous in some scenarios, and level five is complete self-driving in every situation. Currently, no company offers true level five autonomy.
Autonomous cars use various technologies to navigate. This includes radar sensors, cameras, internal GPS, laser rangefinders, software, and a lidar unit. The car uses GPS for location and other sensors like lidar and radar to create a virtual map of its surroundings. Cameras provide visual data, identifying other vehicles, pedestrians, and anything in the road. The car processes this information to make navigation decisions, sending commands to the braking, throttle, and steering systems, repeating this process many times per second.
Many companies are racing to develop autonomous vehicles. Google's Waymo is testing self-driving minivans and Jaguars in California and Arizona, focusing on ride-sharing. Uber is also testing autonomous Volvos through virtual simulations, aiming for public deployment by 2020 with human oversight. Apple's Project Titan remains secretive but is actively hiring and making acquisitions in the field. Most of these efforts focus on shuttles and ride-sharing.
Beyond ride-sharing, autonomous delivery is a significant area of development. Giants like Amazon, FedEx, and UPS are researching driverless trucks to reduce delivery costs. Domino's is even partnering with Nuro to test pizza deliveries with self-driving pods in Texas. Autonomous delivery could be a primer to gain public trust in self-driving technology. Companies like TuSimple already have 51 self-driving trucks on the road for cargo transport, accompanied by human drivers for safety.
Despite breakthroughs, public safety concerns remain, and the technology isn't fully mature. Achieving level five automation in all conditions is challenging. However, level four and level five automation for specific applications like shuttles and deliveries are likely to become common sooner. The industry needs to demonstrate the viability and safety of these technologies to gain public acceptance and move forward.
