Intervention isn't necessary when following a car through an intersection. However, drivers need to press the accelerator pedal or gear stalk to prevent the car from stopping at green lights, and the system had to be re-engaged manually after each stop, which made us question whether or not this was indeed progress. In the spring of 2020, Traffic Light and Stop Sign Control Beta was added to cars that had opted for Full Self-Driving, which allows the car to stop for traffic control. It's added the ability to recognize stop lights, stop signs, traffic signs painted on the road, cones, trash cans, and pedestrians, which it displays to the driver on the left side of the central touchscreen. The driver-assist system has evolved over the roughly 28,000 miles we've spent with our Model 3. Our aim is to repeat this loop once Full Self-Driving becomes available (as well as its subsequent updates over time) and show how the car's performance improves-or gets worse-over time.įor this first test, we drove the 70-mile loop around our Ann Arbor, Michigan, headquarters under optimal weather conditions. Our loop introduces numerous difficulties for driver-assist systems to navigate, including roundabouts (humans in our area haven't figured these out yet, either), 90-degree highway curves, cloverleaf interchanges, complex highway-to-highway merges, and urban areas with lots of pedestrian and vehicle traffic. But still, many accidents have occurred while drivers were using the existing technology, and the National Highway Traffic Safety Administration (NHTSA) has investigated numerous instances. Soon, Musk says, owners will gain access to the technology the name promises, although even Tesla admits it still won't be fully self driving. And it could be subscription based in the future.
