The National Highway Traffic Safety Administration (NHTSA) has recently launched an official investigation into Tesla's "Full Self-Driving" (FSD) system. It is reported that the investigation involves approximately 2.41 million vehicles, covering multiple models. The reason is that Tesla vehicles with FSD enabled have been involved in collisions with casualties in areas with reduced visibility. The FSD beta was launched in 2020 with the goal of achieving truly autonomous driving without human intervention, but according to current standards, it is only at Level 2, still requiring drivers to actively monitor road conditions. This creates a stark contrast with the "Full Self-Driving" naming.

Although Elon Musk has stated that new models next year will be equipped with unsupervised full self-driving software and will be on the roads in California and Texas, the current investigation into FSD casts uncertainty on its development path.
