The MB Drive Pilot only works at ridiculously low speeds (under 40 mph), on select highways, no sharp turns, no weather, no construction zones, lanes clearly visible, etc. It's laughable to compare it against FSD which works everywhere. FSD has been flawless when driving on such easy conditions for years.

Are you assuming MB Drive Pilot couldn’t also work pretty well outside of its design domain? This argument is always so silly because it’s just an argument about the correct way to build a safe control system (i.e. with guaranteed performance characteristics in a defined operational domain) versus the incorrect way to do it (just kinda work over an ambiguously defined set of conditions and hope you don’t kill too many innocent people to cripple your business).

  > Are you assuming MB Drive Pilot couldn’t also work pretty well outside of its design domain? Yes,that's a suppressed fact, not an assumption. It just follows the car in front. Check my other comment. https://news.ycombinator.com/item?id=42384114 https://news.ycombinator.com/item?id=42384114

    Umm, yeah. Maybe I wasn't clear. MB Drive Pilot is designed not to attempt to operate outside of a well-defined domain. It will, by design, not operate in a way that is unsafe or in a context in which it's unsafe. You are arguing the system would perform worse in contexts in which you have not seen it perform (because its designers decided to prevent it from such attempts). What evidence do you have for your argument? Restated: You are assuming that if Mercedes engineers had a similar appetite for putting millions of innocent people at risk by operating in unreliable contexts, that their system would perform far worse than FSD does. On what basis do you make that assumption?

      > What evidence do you have for your argument? The fact that their software is written only to just follow the car in front, and completely and immediately give up if there's no car in front or one cannot be seen due to it being dark or bad weather, on premapped roads. Meanwhile FSD has repeatedly shown that's it's capable of driving without a car in front. You can watch YouTube videos of FSD driving without a car in front for thousands of miles on non-premapped roads. What makes you think Mercedes would be better at doing that?

        What makes you think that MB doesn't have the same capability, but they aren't willing to ship a half-arsed highly dangerous, people killing feature like some other companies do? Unlike any of their competitors, they assume full legal liability for their car's behavior while Drive Pilot is enabled. MB also has a luxury brand reputation to maintain. When they ship a major feature like that, it absolutely has to work 100% as advertised.

If someone gets killed when the system is driving, there is no legal framework for you as a driver to escape criminal penalties. Who at MB are they going to jail for it? Can UPS indemnify their drivers from involuntary manslaughter charges?

        I've worked on competitors to the mb system from legacy auto; generally the way we work is make the best possible system for the long term, then limit the odd to meet safety, regulatory, and brand risk requirements. So there will be a system happily running producing target driving paths, but some monitoring system disables in the case with no car in front. I would guess that the mb system is in fact ok without a car in front, but didn't hit their appetite for risk yet.

FSD isn't driving though, you're driving. Mercedes is driving itself and you have 10 seconds to takeover. Huge difference between level 3 and level 2. One is self driving and one is just a drivers aid.

  > Mercedes is driving itself and you have 10 seconds to takeover. Huge difference between level 3 and level 2. One is self driving and one is just a drivers aid. None of that is true, it just follows the car in front in slow moving traffic during daytime in good weather on premapped roads and cannot even change lanes. No car in front anymore? It completely fails to "self"-drive. These limitations are taboo to talk about because the Mercedes system is used as an anti-Tesla talking point, you can get permanently banned from Reddit and BlueSky for bringing it up. Thats why so many people think its a great system. Edit: Downvotes for bringing up inconvenient facts.

    I'm very much aware of how Drive Pilot doesn't handle most cases: in my comment I described it as "super limited" and linked to where Mercedes describes the details. But within the range of cases where the Mercedes system is applicable (which recently went up to 59mph in Germany [1]) it's solidly better than the Tesla system because Mercedes did the engineering to make it reliable enough that you don't have to supervise the car's driving. If I had a highway commute in stop-and go traffic I'd be comfortable reading in a Mercedes, but not in a Tesla.
