Tesla CEO Elon Musk has been promising customers a driverless vehicle since at least 2016. While the company hasn't delivered on that promise, Tesla lets thousands of employees and customers try new and unfinished driver assistance features on public roads in the U.S. through a program called Full Self Driving Beta, or FSD Beta. Only Tesla owners who have the company's premium FSD driver assistance system installed in their cars can join the FSD Beta program. Owners must then obtain a high driver-safety score, as determined by Tesla software that monitors their driving habits, and maintain it to keep FSD Beta access. No safety certification or professional training is required.
