Elon Posts Tesla FSD 12.4 is Near While FSD 12.3.5 Starts Release

Elon Musk reasserts that Tesla FSD 12.4 will be another big improvement and will be released soon.

Tesla FSD 12.4 will have the driving data learned from another billion miles of driving from the one month free trial for 2 million users.

The new driving data will be from many new drivers who were inexperienced using FSD 12.3.X. The new drivers had more disengagements.

Tesla FSD 12.4 should also have major features that should complete the major gaps in FSD capability. Those major features should be around driving in reverse, handling flashing red lights providing a more comfortable ride that is safer but also feels safer to passengers.

The list of important milestones for Tesla FSD are a list I made last month.

I would consider Tesla FSD 12.4 as a huge success if the following happens:
It is released in 1-3 weeks and with fewer disengagements than one in 500 miles or one in 1500 miles that would mean fewer than one incident per week or one incident per month of driving. It would need to take two weeks to a month to get testing confirmation of those advances.

  1. A Tesla driver up here in Seattle killed a motorcyclist yesterday while the car was on autopilot and the driver distracted on his phone. He was arrested for vehicular homicide.

    I own a Model 3… am a fan. I’m sure the vast majority here are good drivers, but as a nightly motorcycle commuter (electric Zero SR w/ 60,000 miles), please please watch the road and be ready to take over.

  2. Been driving using 12.3.4 on long trips over an hour it begins to hug the center line
    Stopped cleaned the camera lens around the car, start driving fine then in about 45 minutes it started the same behavior.

    On offset intersections it will switch lanes without signaling, with or without other cars around. This said it is worlds better than 11 or the initial release of 12

  3. My wife’s modely y got the FSD beta back on April 1st and I’ve been driving it on weekends and have an observation. As long as I have to have my hands on the wheel and my eyes on the road I’m going to intervene anytime the car does something I don’t agree with (change to the right lane behind a slow truck for example). These things are not unsafe and the trip would end just fine, it’s just not how I would do it. When FSD allows me to go heads down on my phone or laptop during a drive, I’ll have many less complaints about how it drives and stop trying to force my paradigm of impatience on the vehicle.

    This is the second time we’ve had FSD on this car. The last time was one of the v11 and it was really not good. This v 12…. is miles better than the last time.

    • The better intervention in the unnecessary lane changes is to cancel the blinker and stop the lane change.

      It still has a long way to go before we’re averaging 1 intervention in 500 miles

  4. We downloaded V12.4.3 April 6th and drove round trip coast to coast in Central Florida, 420 miles, with no intervention. The only issues were one navigation error and a few parking issues.

    Way to lead the charge Tesla Team!!

  5. For the latest release, the miles to driver intervention is 21. Miles to safety critical intervention in the city is 110, down from 284 miles for 12.3.

    Brian, how do you expect that 21 miles jumps by a factor of 25 from fsd 12.3.3 to fsd 12.4? Miles to intervention has gone down from both previous versions. Why would it go up so dramatically this time? Makes no sense…

    • Because 12.4 has one billion more miles of data than 12.3. There was no real gain of data in between 12.3 and 12.3.4. Just small corrections (f.e. removed bad data). Easy as that.

    • It does make sense.
      A ton new FSD users have 1 free month, and they are brand new to self driving, which can be a scary thing. So naturally they are nervous, and are hitting the breaks (disengaging) more then an experience user would.

  6. “Elon: FSD Beta 12.3 is such a big release it should arguably be called V13”
    “Elon: 12.4 is a big release. Should arguably be 13.”

    He said the same thing for 12.3.
