Increase Lane Change Timeout after Initiation


Now Implemented!


When using EAP/FSD and you initiate a lane change using the blinker (3-blinks or hard blinker on), complete the lane change without returning to the current lane, presuming it’s safe.


With EAP, when you press the blinker, Auto lane change is initiated. The lane change times off after a few seconds, which is often the case even with medium incoming traffic. Moreover, it cancels an initiated lane change after starting to move over and leaving the centerline, which is very dangerous behavior since you indicated to the car in the back of you that you want to change lane. Autopilot cancels this started lane change and swipes back to the original line after a short timeout.

Disable the timeout or increase the timeout to at least 10 seconds.

Especially, don’t timeout if the lane change is physically initiated!


Implemented in the USA.  Tested multiple times with version 2021.32.22 without any issues. May take longer in other countries.

"According to Europe’s new regulations, lane change maneuvers must not be initiated before a period of 3 seconds and not later than 5 seconds after deliberate driver action. This means that once initiated, the lane change maneuver must be finished in less than 5 seconds. This regulation becomes an issue in real-world scenarios. For example, if drivers start indicating a lane change and there’s a car in an adjacent lane that won’t give way, the maneuver must be aborted within 5 seconds. If a Tesla hits the 5-second mark while this is happening, the vehicle must abandon the lane change attempt and return to its original lane. These restrictions, according to Peeters, have resulted in his Model S swerving to return to the center of its original lane as soon as it hits the 5-second mark."
