What's in Tesla's software update 2019.40.2

Last updated: Dec. 25th, 2019. If you’re looking for information about Tesla’s latest software update, check out update 2019.40.50.1.

[Dec 10, 2019] 2019.40.2.1 update started rolling out to the masses today. Our sources indicate that it’s pretty similar to the 2019.40.2 update, which was only made available to a few people. See below for more info about what’s in 2019.40.2.1.

2019.40.2 started rolling out on Dec 5, 2019, after the 2019.40.1.1 update was stopped a couple of days ago. We believe that the 2019.40.2 update is a patch release- as some Tesla owners reported problems with the previous release- but this time, on top of fixing what made them stop the previous rollout, Tesla is also introducing two new features.

Thank you @TeslaRiders for sharing the release notes with us. Here you go:

We have heard from Tesla owners with Autopilot 2.5 and Autopilot 3, and both have received the same new changes with the 2019.40.2 update:

Adjacent Line Speeds:

When your vehicle is moving at a significantly faster speed than vehicles in neighboring lanes, Autopilot now automatically reduces your driving speed.

I’m definitely intrigued to see how this is going to work when you’re in the HOV lane or when exiting the freeway, where speeds are clearly slower than in adjacent lanes.

Autosteer Stop Sign Warning:

Your car may warn you in some cases if it detects that you’re about to run a stop sign, in addition to stop lights, while Autosteer is in use.

It’s great to see that the car now detects and reacts to stop signs. I hope it warns you when it’s not too late. To be blunt, I feel it’s not very good with traffic light warnings today.

Unfortunately, Autosteer Stop Sign Warning is only available in the United States.

These features come in addition to Automatic Wiper Improvements, Automatic Lane Change Improvements, and Supercharging Improvements, all introduced last week with the 2019.40.1.1 update.
