Lane changes

Tesla’s Auto Lane Change feature is included in Full Self-Driving (FSD) and Enhanced Autopilot, but not in Autopilot. Auto Lane Change assists in moving to an adjacent lane on the highway when Autosteer is engaged. In addition, Navigate on Autopilot (NoAP), also included with FSD, actively guides your car from a highway’s on-ramp to off-ramp, including suggesting lane changes, navigating interchanges, automatically engaging the turn signal and taking the correct exit.

Blinker detection in AP when merging in traffic

We’d all love our Tesla to predict when cars are merging, specially when there’s a lot of traffic. It seems this feature is already in development, according to Elon Musk’s tweet.

Changing lanes away from cones

As far as I know, this is only for HW3 cars running 2019.36.1 or later. For what is worth one person on Twitter told us that if there are cones on both sides of the road the car keeps on switching lanes, I guess there is still some unwrinkling to do.

Example of emergency lane departure avoidance working as intended

Onwer ended up with his head in the clouds (his words, not mine) for a moment, and didn’t notice how the road was curving. The emergency lane departure feature saved him from an expensive repair.

First look at Tesla v10 release notes: Here’s what’s coming

v10 got released to folks in the Early Access Program a few days ago, here’s what’s new:

  • Tesla Theater: As Elon advanced on Twitter, Tesla are getting Netflix and YouTube through dedicated apps
  • Caraoke: Card + Karaoke = Caraoke. This feature allows users to sign along their favorite tracks. According to the release notes, this feature is only available while in park. We think it’d be fun to have it while driving too, for passengers only of course
  • Cuphead: Tesla Arcade is getting some serious games, Cuphead was announced a while ago and now is hitting the cars
  • I’m feeling lucky / I’m feeling hungry: As we advanced a few weeks ago thanks to greentheonly, these two options are now part of the navigation
  • Maps improvements: When searching for a destination the autocomplete now shows the distance to the place
  • Sentry mode improvements: Sentry mode now records videos in a new folder to easily distinguish between Sentry recorded videos and Dashcam videos that you saved. It also overrides older Sentry videos when full
  • Joe Mode: Quieter chimes to avoid waking up your Joe’s family
  • Driving visuals: Additional objects, lane lines, and adjust the zoom and viewing angle
  • Automatic lane change: The visualization now displays where the car is going

Mad Max mode is real

Elon’s screenshot has revealed not only blind spot detection with different modes when changing lanes including Mad Max mode (woot?!) but also:

  • Follow nav: The car would follow the navigation directions
  • Blinker to fork: some people seem to think that this is the possibility of telling the car where to go on a fork by using the blinker
  • ULC: maybe Unassisted Lane Change?

More news about v9 release

The wide release of v9 isn’t here yet but there is a lot of new information about it - as you will see by the amount of videos and photos below. Elon Musk said “Got to make sure we iron out the details though. Long tail of tricky edge cases”. Some news since last week are:

  • Confirmation that EAP in v9 uses the repeater and the b pillar cameras.
  • New neural network for the rearview camera. Rumors before v9 were that it wasn’t going to be used for EAP or FSD since it didn’t have any neural network, it seems like it is going to be used!
  • ‘Navigate on AutoPilot’ but… ‘Automatic Lane Change’ is gone. The driver will have to do a single pull on the AP stalk to confirm the lane change. From there the car will turn on the blinker, change lanes, and turn it off.
  • Allows lane changes at any speed (not just above 30mph), and will slow down and find a place in traffic to merge. appleguru used it today in heavy traffic to merge in moving 2-3mph and was really impressed.
  • Uses maps to help with navigating tricky road sections.

Tesla v9 Beta: AP drive by nav feature

As we stated above “Auto Lane Change” isn’t getting shipped in the first release of v9 but here is an awesome video by dennis_d from TMC. These are his words:

“Car drives itself. Mad Max mode enabled. Turn confirmation is disabled. The car basically drives itself, whenever you see a blue line in the middle it’s driven by autopilot.

It actually drove pretty well, there were couple moments where I had to take over, cause I thought it going to do something stupid like turn between two cars in the very tight space (I was on Mad Max mode tho). Had two moments with phantom braking next to a track.

All the turns AP was doing itself, I didn’t touch the stalk. There were two moments with red lines where I wanted to overtake (red lines) but it seems to handle it like a boss.”
