![Tesla Continues Rollout of FSD 12.4.3; Resets Strikes [Update: Another Wave Going Out Now]](https://cdn.statically.io/img/www.notateslaapp.com/img/containers/article_images/fsd-beta/2022.45.10-fsd.png/1b2daac4e91656345d5c7bae5c3ab487/2022.45.10-fsd.jpg)
FSD Beta v12.2.1
FSD Beta v12 upgrades the city-streets driving stack to a single end-to-end neural network trained on millions of video clips, replacing over 300k lines of explicit C++ code.
Over-the-Air Recall: Telltale Text Size
As the remedy for US Recall 24V-051, this update to your vehicle software increases the text size of three telltales.
After installing this vehicle software update, you don't need to take any further action for this recall.
Removal of TACC with FSD Beta
In the Autopilot menu, you can pick between Traffic-Aware Cruise Control (TACC), Autosteer and FSD.
If you choose FSD, then Tesla is now requiring single-pull (or single-click for vehicles without stalks), to be chosen as the activation method.
Single-pull activates Autopilot with a single tap of the right stalk. In this case, a double tap doesn't do anything to prevent confusion.
Since a double tap doesn't do anything, the driver is no longer able to activate TACC without turning off FSD Beta in Autopilot settings.
U-Turns
With FSD Beta v12, the vehicle is now able to complete U-turns when they're part of the route.
Automatic Speed Offset
Automatic Set Speed Offset allows Autopilot to drive at the speed that it determines is most natural. This considers factors like road type, traffic flow, environmental conditions, speed limit, and the selected Full Self-Driving (Beta) Profile setting (Chill, Average, or Assertive).
This new setting is off by default, but can be turned on under Controls > Autopilot > Automatic Set Speed Offset.
This gives the vehicle more freedom when determining its speed, such as when passing or keeping up with other vehicles.
