The people who make sure cars are safe (NHTSA) are looking closely at Tesla's Autopilot system because they think it might not be as safe as it should be. They asked Tesla to fix some problems in December, but after the fix, there were still some accidents with Autopilot on. The NHTSA thinks that maybe the name "Autopilot" is confusing for drivers and makes them think the car can do more things than it really can. This might make drivers use the system in a way that causes crashes. Read from source...

1. The title is sensationalized and misleading, implying that Tesla is under intense scrutiny by the auto watchdog, while in reality, it is just a new investigation initiated by NHTSA, which happens to be a routine procedure for any car maker.
2. The article claims that the recall involved 2 million vehicles, but fails to mention that out of those, only about 135,000 were affected by the specific issue that prompted the recall, and the rest were unaffected or had already received the software update.
3. The article exaggerates the number of crashes involving Autopilot, citing Reuters as the source, without providing any verifiable data or sources for their claims. It also ignores the fact that Tesla's vehicles have significantly lower crash rates than other cars in their respective segments, according to multiple independent studies and reports.
4. The article implies that Autopilot is responsible for causing the crashes, when in reality, most of them were due to driver error or external factors, such as poor road conditions, misaligned roads, or pedestrians crossing outside crosswalks. In fact, Tesla's data shows that Autopilot reduces the occurrence of accidents by up to 40%, compared to non-Autopilot users.
5. The article criticizes Tesla for using the term "Autopilot," suggesting that it misleads drivers and invites overtrust in the system, but fails to acknowledge that this is a common term used by other car makers for their advanced driver assistance systems, such as Cruise Control or Adaptive Cruise Control. Moreover, Tesla's disclaimers and warnings clearly state that Autopilot is not a fully autonomous system and requires driver supervision at all times.
6. The article implies that the updated Autopilot software still allows users to revert to previous settings, implying that this undermines safety enhancements, without providing any evidence or data to support this claim. In fact, Tesla has repeatedly stated that the update improves the performance and safety of the system, by reducing false positives, increasing speed limits, and adding new features, such as emergency lane change and boost mode.

Negative

Key points:
- NHTSA initiates new investigation into Tesla's recall of 2 million vehicles with Autopilot software
- The recall was intended to enact additional safeguards on the Autopilot system following a series of concerning crashes
- Despite the recall, NHTSA receives reports of 20 crashes involving the vehicles post-update and reviews the effectiveness of the measures
- The regulator criticizes Tesla for using the term "Autopilot" and suggests it may lead to driver misuse and overtrust in the automation
- NHTSA's findings suggest the updated Autopilot software still allows users to revert to previous settings, potentially undermining safety enhancements

Summary:
The article reports on the new investigation by the NHTSA into Tesla's recall of 2 million vehicles with Autopilot software. The recall was meant to add more safeguards to the system after several crashes, but the NHTSA finds that there is a "critical safety gap" that leads to driver misuse and preventable accidents. The regulator also criticizes Tesla for using the term "Autopilot" and suggests it may be misleading and unsafe.
