He seems so obviously correct that I can’t fathom how any engineer could see things otherwise.

As an engineer you should care about cost and other tradeoffs. At this point Waymo is not much more than an exorbitantly expensive tech demo. I sure hope that one day it is more than that.

Tesla has a million cars on the road. It is a technology people can use and afford and it is working.

comma.ai sells a device for $1000 that can be installed on the majority of cars sold in America.

It's still too early to say much about Waymo.

Musk seems more of a marketer than an engineer to me, even though he's always characterized as one.

Musk has degrees in economics and physics. My undergrad is in physics and my dad is an engineer. They are definitely different skillsets.

When I decided to build a treehouse for my kids, I came up with a clean sheet design. My dad saw my drift and walked me through a redesign the preserved the core idea. And then my neighbor, a general contractor, supervised the build (and pretty much doubled every safety margin along the way). My other neighbor (a self-employed roofer) did the crazy bits.

I would be inclined to credit Musk with broad outlines and I would give him credit for being able to participate in the engineering process by asking some sensible questions. I would not be inclined to credit him with imposing tried-and-true design methods and constraints. Similarly, I would give him credit for broad outline path-to-profitability. I would not give him credit for day-to-day diligence of double-entry accounting that the CFO worries about or the contract negotiations his PMs answer to the CFO's staff for.

Is anyone else confused on the merits of Waymo's argument? They differentiate "driver assistance" from "fully autonomous" systems in that Tesla somehow can never achieve the latter because they have developed the former. The only specific reason for this that I could find was a mention of LiDAR and how Waymo sees it as indispensable. > Krafcik says that Waymo has largely completed technical work on its self-driving s…

The core point is you can't go smoothly from a driver assist to fully autonomous. They're just completely different from the point of view of the reliability of the software you need. A huge amount of things with driver assist you can write off as 'the driver will take over'. There's not a specific part of you can point to and say 'that's what will stop them', so much as the entire design of the system needs a different level of consideration because it becomes so safety critical, as opposed to safety-enhancing (autonomous driving is probably the most complex safety critical design ever attempted, by at least an order of magnitude. Driver assist is way easier by comparison). It affects the attributes of the sensors, the design of the neural networks interpreting those sensors, the high level design of the decision making of the whole vehicle, the low-level design of the electronics, basically everything.

Tesla hasn't put forward a plan which indicates their full autonomous development is going to be anything other than a continuation of their driver assist work (and it's certainly frequently and incorrectly stated that the state of their driver assist puts them ahead in the race to full autonomy), and if they want to be credible to those familiar with the challenges involved, they need to actually show something more than that.

I worked with a self-driving product team a couple of years ago. Tesla's approach was looked upon with suspicion and often openly mocked.

Tesla's entire self-driving strategy is led by Karpathy, who while brilliant, is an under-experienced researcher with a narrow expertise in large scale 2D CNNs. Tesla (and Comma.ai ?) seem to be the only groups that find Lidar unnecessary for L5 self-driving.

I completely agree with this article. I avoid using cruise control and auto-lane-keep for the same reasons. Either I am in control or I am not. Anything in between is a recipe for distraction, and by proxy, disaster.

On the other hand, I can see Tesla's strategy paying off as a low probability win but no lose situation. If 3d lidar is necessary, then I think Waymo (Alphabet) is closest to self-driving success. If they 'win', I see them licensing their tech to every other manufacturer. In such an outcome, Tesla ends up no worse than all of its competitors. It is a no-lose scenario. However, in the unlikely scenario that 2D videos are sufficient for L5 self-driving, Tesla wins BIG. No one will be even close, especially due to the scale of 2D data that they have gathered.

The argument is that they are not even in the same category of technology complexity.

Which is very reasonable.

Tesla's real-world deployment of autopilot is frankly probably an advantage of sorts. And maybe starting with those realities is 'good path'.

But it doesn't change the nature of the fact the gap is quite big.

The whole point is they aren't actually doing what waymo is setting out to do, and it doesn't matter how many cars tesla has with driver assist it won't really help them get to full autonomy.

Earlier quoted context omitted.

People die all the time, there are even higher profile cases like the Apple Engineer who slammed in the barriers at full speed: https://www.kqed.org/news/11801138/apple-engineer-killed-in-... There are some spectacular failures that are very scary because the car does something that a person would never do, unless unconscious, like this one: https://www.youtube.com/watch?v=LfmAG4dk-rU You don't hear much about it pro…

Wow that second one is terrifying. Particularly since that was only 7 months ago!

> They believe that lidar sensors will be indispensable to get early self-driving vehicles on the road.

I agree with this assessment. It seems to me that lidar has a consistency in its ability to detect objects that computer vision based techniques just don't have. While cameras may eventually be able to achieve the same thing, I would argue that lidar will always be as safe or safer, and for that reason I think it will be the only acceptable version if self driving breaks out in the next few years.

drivers came to trust it way too quickly. Drivers who were supposed to be closely monitoring the system instead spent their time looking at their phones, putting on makeup, and other distractions. Really hope no one dies because of Tesla's autopilot. This is a real risk. Quoting from below: if the car does it right 99% of the time it's just human nature to stop paying attention. The article makes a great point that s…

I mean people have already died sleeping with it on. But it’s also likely saved lives based on their deaths per mile number.

I’m not sure if I feel easy about this “statistic” - deaths per mile?? These are humans, and more importantly to the business - paying customers.

If my product has the possibility of killing my customer, I’d probably not be comfortable with making it market ready (without massively improving its safety features).
