This has been billed as the “first self-driving car fatality,” but the truth is that the Tesla wasn’t designed to be a self-driving car. Instead, it is what is technically known as an SAE level 2 autonomous car, which is defined as “driver assistance systems of both steering and acceleration/ deceleration using information about the driving environment and with the expectation that the human driver perform all remaining aspects of the dynamic driving task.”
