Expecting people to be able to behave like machines is generally the attitude that leads to crash investigations.

Imagine you're the guy who invented SawStop, the table saw that can detect fingers touching the saw blade and immediately bury the blade in an aluminum block to avoid cutting off someone's finger. Your system took a lot of R&D, it's expensive, requires a custom table saw with specialized internal parts so it's much more expensive than a normal table saw, but it works, and it works well. You've now got it down that someone can go full-speed into the blade and most likely not even get the smallest cut. Every time the device activates, it's a finger saved. Yeah, it's a bit expensive to own. And, because of the safety mechanism, every time it activates you need to buy a few new parts which aren't cheap. But, an activation means you avoided having a finger cut off, so good deal! You start selling these devices and while it's not replacing every table saw sold, it's slowly being something that people consider when buying.

Meanwhile, some dude out of Silicon Valley hears about this, and hacks up a system that just uses a $30 webcam, an AI model that detects fingers (trained exclusively on pudgy white fingers of Silicon Valley executives) and a pinball flipper attached to a rubber brake that slows the blade to a stop within a second when the AI model sees a finger in danger.

This new device, the, "Finger Saver" doesn't work very well at all. In demos with a hotdog, sometimes the hotdog is sawed in half. Sometimes the saw blade goes flying out of the machine into the audience. After a while, the company has the demo down so that when they do it in extremely controlled conditions, it does stop the hotdog from being sawed in half, but it does take a good few chunks out of it before the blade fully stops. It doesn't work at all with black fingers, but the Finger Saver company will sell you some cream-coloured paint that you can paint your finger with before using it if your finger isn't the right shade.

Now, imagine if the media just referred to these two devices interchangeably as "finger saving devices". Imagine if the Finger Saver company heavily promoted their things and got them installed in workshops in high schools, telling the shop teachers that students are now 100% safe from injuries while using the table saw, so they can just throw out all safety equipment. When, inevitably, someone gets a serious wound while using a "Finger Saver" the media goes on a rant about whether you can really trust "finger saving devices" at all.

Anyhow, this is a rant about Waymo vs. Tesla.

I mean Waymo is way better at their job than Tesla and are more responsible, but this rant makes them out to seem perfectly safe. Whilst they are miles safer than Tesla, they still struggle with edge cases and aren't perfect.

Behave like machines? Wtf are you on about? It's paying attention and preventing accidents. Like a train conductor does. Or a lifeguard. Or a security guard. I get the tesla hate, but this is ridiculous.

Lifeguards have very short periods of diligence before they take mandatory breaks in an extremely controlled environment. Train conductors operate on grade separated infrastructure. Security Guards do not have to take split second action or die.

Putting a warm body in a mind-numbing situation and requiring split second response to a life or death situation at a random time is a recipe for failure.

I saw the Tesla Robotaxi:

• Drive into oncoming traffic, getting honked at in the process.
• Signal a turn and then go straight at a stop sign with turn signal on.
• Park in a fire lane to drop off the passenger.

And that was in a single 22 minute ride. Not great performance at all.

Well, put the drivers on a similar mandatory break schedule. Done.

So it emulates a standard BMW driver. Well done.

Lifeguards take breaks every ~20 minutes, not just to look down or zone out, to get up and move around. And again, are in an extremely controlled environment looking for a very small number of specific problems.

Elon is making programmers sleep at their desks.

Doesn't sound too safe

Human drivers struggle with edge cases also. I've seen a lot you drive, and as an old medic who has done his share of MV accidents, I can tell you y'all ain't that good at it.

While I have no dog in this hunt, all any self driving vehicle needs to be is just a bit better than a human one to be an improvement and a net win, (never let perfect be the enemy of good enough). And historically, as soon as any new technology becomes affordable, humans adopt it and use the snot out of it. The problem is, humans aren't very good at projecting future harm that any new tech tends to drag along with it.

He meddles. That much is apparent. The cybertruck is obviously a top down design as evidenced by the numerous atrocious design compromised the engineers had to make just to make it real. From the glued on "exoskeleton" to the hollowed ALUMINUM frame to the complete lack of physical controls to the default failure state turning it into a coffin to the lack of waterproofing etc.

A good example is ADHD. I have severe ADHD so I take meds to manage it. If I am driving an automatic car on cruise control I find it very difficult to maintain long term high intensity concentration. The solution for me is to drive a manual. The constant involvement of maintaining speed, revs, gear ratio, and so on mean I can pay attention much easier. Add to that thinking about hypermiling and defensive driving and I have become a very safe driver, putting about 25-30 thousand kms on my car each year for over a decade without so much as a fender bender. In an automatic I was always tense, forcing focus on the road, and honestly it hurt my neck and shoulders because of the tension. In my zippy little manual I have no trouble driving at all.

Are you me? I love weaving through traffic as fast as I can... in a video game (like Motor Town behind the wheel). In real life I drive very safe and it is boring af for my ADHD so I do things like try to hit the apex of turns just perfect as if I was driving at the limit but I am in reality driving at a normal speed.

Part of living with severe ADHD is you don't get breaks from having to play these games to survive everyday life, as you say it is a stressful reality in part because of this. You brought up a great point too that both of us know, when our focus is on something and activated we can perform at a high level, but accidents don't wait for our focus, they just happen, and this is why we are always beating ourselves up.

We can look at self driving car tech and intuit a lot about the current follies of it because we know what focus is better than anyone else, especially successful tech company execs.
