Maybe this doesn't beep at you if you take your hands off the wheel? And people think that is a good thing?

My car judges it if I have put in any manual inputs over the past 10 or so seconds then it starts complaining. Which is seemingly reasonable however there's plenty of nearly perfect straight aways where there's nothing to do for it or me. It would be nice if it had a system where if it isn't doing anything, it doesn't think I'm not doing anything either.

Except those straight, boring roads that require no input are also exactly where and when I most want to use autopilot. This means I have to manually adjust to keep the car happy, instead of letting the well-aligned car just carry on. Autopilot ends up being more work, and more annoying, than just driving myself

It’s NOT self driving. It’s level 2 driving assist. Really good one, but that has nothing to do with self driving. You are driving the car all the time, it’s only assist that can (and will) try to kill you (and others) with 0 notice if you don’t pay attention.

> Really good one ... that can (and will) try to kill you (and others) ... I'm afraid to ask about the bad ones.

Ironically - bad ones will effectively try to kill you less.

That’s the thing about any automations that are just aides. Humans are extremely bad at monitoring machines, and if aide system is good enough that trick you into thinking it’s actually stand alone and in control, you get complacent very fast, stop pay attention as you convince yourself that automation got it.

So bad level 2 driver assists are so bad, that no one will get complacent, as they give you only very minor help. Really good ones (like comma) can trick you into thinking that they can do much more than they’re designed to do.

Are they still being extra and only asking about Putnam scores during interviews?

we hire through https://comma.ai/leaderboard and i think our interviews are relatively chill never heard of anyone asking for anything like that

This was back around 2017-19 (can't remember the exact year), but it was definetly pre-Covid and left a bad taste in my mouth, just like Jane Street and FTX at the time - especially given that your then competitor Deepscale didn't have that style of interview.

There's a few Lex Fridman podcasts with George Hotz, the founder. Highly recommend them: #31 https://www.youtube.com/watch?v=iwcYp-XT7UI #132 https://www.youtube.com/watch?v=_L3gNaAVjQ4 #387 https://www.youtube.com/watch?v=dNrTrx42DGQ

No idea how Fridman manages to bring on the type of high profile guests that he does. Guy does not ask good questions and has the charisma of a wet rag,

Huh, I'm the exact opposite. With the exception of Hannah Fry's work at deepmind (where she acts as a charismatic proxy for the more nerdy guests), he is by far the best interviewer on technical stuff (AI stuff mostly, but some early robotics stuff as well). He knows the field, he asks pertinent questions and more importantly he knows when to just let the speaker speak.

Compared to someone like Dwarkesh, it's night and day. There's a fine line between pushing the guest and just interrupting them every 2nd thought to inject your own "takes".

Ok that was probably unnecessarily snarky I hope you don't take offense, but it seems the hacker spirit has been fading more often from this site, we used to replace stuff with inferior versions just to see if we could.

Unfortunately, a quick google seems to say no one's ported Doom to the Comma hardware just yet!

Lane follow? Does it have lane discovery? There was snow on my commute this morning. 4-land highway was basically follow the leader. Pick some line where you think there is the most traction and stick with it. I have yet to see footage of an autodrive system in such a situation.

Nobody is claiming that this will work in that situation, but there are thousands of much more common situations where it does work and makes driving more safe and enjoyable.

Guests don't care about charisma, they care who your previous guests were. He early on got Elon Musk as a guest (AFAIK by writing a paper that was overly favorable to Tesla) and managed to snowball that into a big podcast. Also guests agreeing to go on your show means they already want to talk about something, so in a way it's more important to shut up than ask good questions.

But then he gets guests spewing utter nonsense and just agrees with them instead of following up. It's unlistenable.

Speaking of hacker spirit... Comma has a lot of restrictions on what software you can load / what changes you can make to the software.

What's hilarious to me is that this scenario is framed as such an impossibly difficult thing for self-driving technology to accomplish. Detecting a car in front of you, and maneuvering left or right is doable without even using advanced models, nevermind the fact that we have them now. The other supposedly impossible feat is for the self-driving car to create a lane when there's been so much snow that the lines and thus lanes aren't visible. Given high quality sensor data, does it really seem that impossibly hard for the computer, which is already competently driving on the road in practice, in SF and Phoenix and LA; it seems impossibly hard for that computer to take the full width of the remaining road, divide in two, assuming it's a bidirectional road, and then create as much lanes + safety margin as can (safely) exist, and then pick one? Proof is in the pudding and all, so here's a 4 year old video showing that comma.ai's capable of that, in the sunny winter but snowy road condition in that video.

Mercedes Drive Pilot (“SAE Level 3”) is certified on some very specific stretches of insterstate in California to not require the driver to be responsible. https://www.mbusa.com/en/owners/manuals/drive-pilot Requirements: - Stop and go traffic (or less than 40mph?) - On some specific sections of highway - Driver doesn’t need to monitor but must be ready to take over with 15(?) seconds of the system requesting > Merce…

that's really dumb of Mercedes take on that liability for little benefit - sell more cars, make more profit? My prediction is MB drops this or goes bankrupt in the next 10 years.

That’s what SAE L3/L4/L4 autonomous driving systems are about. The car takes full responsibility for a given set of conditions (ODD).
