Tesla Full Self Driving Beta V10.11.2 — Is it better or worse? Answer: Yes!

On December 1, 2021, I passed Tesla’s safety test and was able to download FSD Beta V.10.5 to my car. I have since downloaded three software updates: V10.8, V10.10 and just now V10.11.2. I use the software every day. The longer I use it, the more I can observe if negative behavior is a one-time event, a rare event, or a consistent failure.

The $64,000 question is, is the FSD beta getting any better? Short answer: I’ve seen several areas of improvement, but other areas where it’s significantly worse. The rest of the article is an updated description of abilities, improvements, and new flaws from my previous articles. Major changes since the firmware upgrade can be found in the “What are the FSD beta flaws, including new ones seen with 10.11.2?” » All updates related to V10.11.2 begin in fat.

What will FSD beta do?

For some routes, it will take you from your current location to the destination you enter in the navigation without intervention. Others will require a minor intervention or two. For periods of high traffic volume and routes with stop signs and/or roundabouts, you will want to step in at predictable times. The most common intervention is to lightly press the accelerator to signal the system to continue when it is too timid at a roundabout or stop sign. The system will then drive straight ahead or steer the vehicle through the turn correctly, as defined by the navigation you have chosen.

How much does it cost?

In 2019, Tesla charged $6,000 for the FSD. The price of FSD gradually increased thereafter. If you want it now, you have to pay $12,000. Elon Musk says the price will continue to rise as FSD improves. If that’s too big a pill to swallow for an unknown capability, Tesla also lets you try FSD Beta as a monthly subscription for $99 or $199 per month, depending on the level of driver assistance you have. have already paid.

You finally have it, how do you keep it?

You are only allowed 5 forced disengages from Autopilot before Tesla disables the software. FSD Beta limits you to 80 mph, if you force a higher gear with the throttle you will get a forced disengagement. If you don’t maintain a slight torque on the steering wheel for a few minutes, you will get a forced clutch. There is a camera just below the mirror looking at you. If you look at the screen to your right or look at your phone for more than about 20 seconds, you will receive an audible and visual warning. I guess if you persist you will get a forced disengagement. You will know you have had a disengage because access to the FSD will be canceled until you stop the car and put it in park. I have a forced disengagement. I was told that I had used a disengage allowed out of 5, but I was never informed of my infraction. My wife also uses FSD Beta frequently on my Model 3 so I pray she doesn’t get any forced disengagement.

What does FSD Beta do well?

  • It is fully automatic and works great at stop lights and turn signals. It stops much better at red lights than the old FSD.
  • With FSD Beta V10.5, your car moves so slowly that it is not useful for normal driving. With V10.8 and later, the behavior at one-way or two-way stop signs is significantly improved. That might be a little cautious for your taste, but that’s okay now. Plus, you always have the option to signal it to proceed faster with the accelerator. It will then move straight ahead or steer the turn correctly depending on your navigation route. With all versions of FSD Beta, the car stops at the entrance to a roundabout even when no car is present. Again, a little pressure on the accelerator solves the problem. Ironically, behavior at 4-way stops is generally better and it moves faster. I think it’s because it doesn’t have to pay attention to cross traffic.
  • With V10.8 and later, the car no longer brakes for a vehicle crossing your path that will be gone by the time you arrive.
  • Your car will steer around a vehicle, cyclist, pedestrian or other object extending partially into your lane if it is safe to do so.
  • Automatic Speed ​​Control: With regular smart cruise, your speed would be reduced to the speed limit when entering a city. With FSD Beta, your speed will also automatically increase to the speed limit when leaving a town.
  • When FSD Beta is first enabled, you will need to manually increase the max speed up to the speed limit, but then the max speed will adjust up or down as the speed limit increases. speed changes.
  • With FSD Beta enabled, you can usually set the speed more than 5 mph above the speed limit if you wish.
  • FSD beta version usually place yourself in the correct turning lane (left, straight or right). I included this behavior last because too often FSD Beta will put you in the wrong lane and can cause you to turn or go straight when it’s not on your route.

What are the flaws in the FSD beta, including new ones seen with 10.11.2?

Phantom braking (worse!)

You can drive on a perfectly clear Interstate highway and FSD Beta will occasionally apply light braking for no apparent reason. Sometimes you’ll get this light braking for a large vehicle approaching on a two-lane road or a large vehicle or trailer parked near your lane.

I have never braked suddenly and I keep my foot slightly on the accelerator to compensate for sudden braking.

Phantom braking is worse with FSD Beta than it was with standard Smart Cruise. I suspect this is happening because the software is now looking for objects in your lane and sometimes misidentifying them. I now frequently experience phantom braking on a narrow, winding road.

Phantom Deviation: (Worse!)

If phantom braking wasn’t bad enough, with V10.11.2 you can also get phantom yaw. You can drive on a perfectly clear two-lane road and the car will swerve as if trying to avoid a non-existent object. It can swerve into the oncoming lane, but only if there is no oncoming traffic. I observed this behavior twice. [Editor’s note: I had phantom swerving a couple of days ago in the brief time I tested V10.11.2. I was on a straight 4-lane divided highway — two lanes in each direction and a large median in the middle — and it was completely empty on my side of the median, in front of me and behind me as far as the eye could see. The car suddenly swerved dramatically for no clear reason, going from the right lane into the left lane and actually toward the median. It seemed as though it would drive into the curb of the median, but I assume it would have found a way to jerk and jar me without doing so if I hadn’t taken over myself as a result of the phantom swerving. — Zach Shahan]

Where does the FSD beta completely fail?

Note: Failures are constant, so I know when to turn off the software and drive manually. Some failures can be caused by errors in the database. However, in item #1 below, it can see stop signs – which I know because they are visualized for me – but apparently does not use visual distance information to calculate position accurately.

  • At some stop signs it will stop 10 or 15 feet too early. (Also observed with V10.11.2.)
  • There is a 1650 W rotating stop sign on Snow Canyon Parkway in Saint George, Utah where FSD Beta will always run the stop sign. Oh my! Note: this is the only stop sign where I’ve seen this behavior. (Confirmed with V10.11.2.)
  • Right Lane Bias: Exiting I-15 at 1600 N in Orem, Utah, 1600 N street narrows from two lanes to one lane at a red light. FSD Beta will consistently not only fail to merge, but will actively put the car in the wrong (right) turn lane. I have now also seen the same behavior in other places.
  • Straight Lane Bias: When turning or crossing an intersection, your car will sometimes turn into a bike lane or other wide lane on the right. It will usually find good ground after about 50 feet. A driver following you won’t know what to expect.
  • Right Side Slant: Especially on a freeway junction when the lane is still double wide, your car will hang on the white line on the right. This is annoying because a normal driver will tend to the left dotted white line where you need to be when the merge is complete. Note: This also happens with standard Autosteer.
  • Parking Behavior: You can hire FSD Beta in a Walmart or UPS parking lot, but good luck finding its way. In tight spaces the steering wheel will shake and shake like a nervous Nellie and it’s as likely to find its way around a blind corner as it is to find its way.
  • Speed ​​bumps: FSD Beta does not always slow down for speed bumps.
  • School Zones: FSD Beta does not automatically reduce speed to comply with school zone speeds when lights are flashing to indicate that is the time of day drivers must obey them.
