Why Do Tesla Fans Say They Don’t Experience Drowsiness & Distraction On Autopilot?
As a Tesla driver who has used Autopilot plenty (for years) and has had FSD Beta for a few weeks, let me try to answer this question first. I’ll offer my 2 cents on what I think is going on here. Then you can read Jennifer’s piece on various data, studies, and logic that explain why Level 2 driver-assist systems can lead to drowsiness and distraction.
First of all, a big part of the reason why those of us using these systems don’t tend to get drowsy or distracted while using them is that using them is somewhat like a stimulating video game, rather than a mundane driving chore. We are watching for where the system works well, where and why it doesn’t, what has changed with each software update, and how far we are to robotaxi-level driving — all interesting stuff that you might say adds some “gamification” to driving and makes us focus more.
Secondly, the system isn’t close to robotaxi-level autonomy. Perhaps some of the videos you see on Twitter or YouTube make you think it is, but I think anyone who has used the systems — especially FSD Beta — knows that the tech in our cars is not close to robotaxi capable. There are so many things we know the car can’t do well that we’re constantly on the lookout for them in order to 1) do them well ourselves or 2) see if the system has learned a bit and can all of a sudden do them like a human or better. For example, just using non-FSD Autopilot, I know that the system doesn’t avoid potholes. So, to avoid potholes, I have to closely watch the road and disengage Autopilot before going over one — actually, I have to do so early enough that I can go around it without jerking the car (which isn’t really a good alternative to going over a pothole in many cases). Avoiding potholes when fully driving the car myself is almost mindless — it’s second nature. However, with Autopilot on, it’s a kind of game, I have to pay more attention to act appropriately in time, and I also have to actually do more physically — disengage (I prefer to do so by pushing the stalk on the right of the steering wheel up), take back full control of the steering and acceleration, and steer around the pothole.
There are various other little things like this. Also, on the plus side, because I don’t have to focus nonstop on keeping the car in the lane, I do get less fatigued (everyone who has used Autopilot for a bit should notice this) and I have more freedom to scan the roadway around me, scan the crossroads, etc. — all of which is often more interesting and stimulating than trying to constantly make sure my car stays right between two white lines. (Yes, the latter is easy, but it’s also more tiring than many of us realize and assume.)
Just on the topic of FSD Beta, the system can be such a nutjob that it’s truly several levels above normal driving in terms of stimulation. You have to be super focused and alert, and you know it. Frankly, whereas basic Autopilot reduces fatigue a lot, I have no doubt that FSD Beta adds significantly to it.
I am clearly a bit biased, though, since I use the system. I think I also have the experience to answer the questions well, but certainly not for all situations and cases. Some people may use Autopilot for long empty stretches of roadway in which there is nothing to really do and they become drowsy and distracted. I could imagine that happening. To provide some other thoughts and information, let’s roll into Jennifer’s piece.
Oh yeah, I’ll also first note that I saw years ago a note that NASA determined several decades ago that even a determined, well trained, intelligent engineer couldn’t stay focused on something for long if there was nothing to do/fix. (Anyone who has seriously tried meditation knows this as well.) That has always been a warning against an autonomous driving system that is very good but not good enough to turn into a robotaxi. The point that is missed at this stage, in my opinion, is that someone using Autopilot/FSD Beta doesn’t have nothing to do, as I explained above — except perhaps in scenarios or places where this problem does arise, like driving for a long time on an Interstate highway where no real interaction or correction is needed for very long stretches of time. I’m yet to experience such a drive, but I presume some might be possible.
Okay, that’s really the end of my comments. —Zach Shahan
In past articles, I’ve written about what I call The Level 2 Attention Problem. The Insurance Institute for Highway Safety (IIHS), like other who had conducted a number of previous studies, found that people get distracted when a level 2 system does the steering and throttle, and get more distracted as they get comfortable with the system. NASA has also studied human-machine interactions over decades, and recently found the same thing again. The last link also references a University of Utah study that put random people behind the wheel of Teslas running Autopilot, and many of them were sleeping. Worse, they weren’t even aware that they were sleeping behind the wheel.
I’ve personally experienced this when using different L2 systems, including almost 5,000 miles on a Kia L2 system that functions very similarly to Autopilot. After a while, it becomes easy to “zone out” while the car does the steering and throttle control, and I found myself trying to fall asleep a number of times. What I realized pretty quickly was that taking the steering task over and leaving adaptive cruise control on was usually enough for my brain to wake back up and feel alert again.
Some People Don’t Believe Me, Or The Studies
Every time I’ve brought this up, readers would comment that they’ve never experienced this in their Tesla. Supposedly, the use of Autopilot makes them feel more awake and aware than usual, and they feel that they’re a much safer driver with the system than without, even on long trips. Even people I respect tell me things like this:
