Tesla began sending out over-the-air software updates for its long-awaited “Full Self-Driving” beta version 9, the definitely-not-autonomous-but-certainly-advanced driver assist system.

As promised by Elon Musk, the software update (2021.4.18.12) began uploading after midnight on Friday, giving thousands of Tesla owners who have purchased the FSD option access to the feature, which enables drivers to use many of Autopilot’s advanced driver-assist features on local, non-highway streets.
