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 a…

Saying he "knows the field" is kind of pushing it. He's good at conversations and that's about it, his actual merits are questionable at best.

Best interviewer is Primagen, a senior engineer with balanced takes that has seen both extremes of life.

> My already comes with built in why would I install anything else? Top voted comment on hacker news btw. 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.

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

No it doesn't?

You can run stock, or any fork simply by providing the URL of the version you want to run.

Where exactly is the restriction?

> he knows when to just let the speaker speak

I think similar to Joe Rogan that's the main value he provides to listeners. He identifies guests that have some veil of intellectualism and provides them with a platform to speak.

However I don't think that makes for an interesting interviewer. There are no challenging questions, only ones he knows will fit into the narrative of what the guest wants to say. I might as well read a 2-3 hour PR piece issued by the guests.

I like Comma. I like geohot (I wouldn't want to work for him I imagine it is intense) but I like the contrary attitude and also the product as seen as demoed on youtube.

He hasn't been running comma.ai since '22, and even left the board just in November.

He's not the type to run a company. He likes to work on code and he works on tinygrad a lot which comma.ai uses.

> Currently, openpilot performs the functions of Adaptive Cruise Control (ACC) and Automated Lane Centering (ALC). openpilot can accelerate, brake automatically for other vehicles, and steer to follow the road/lane. [1] [Some of the] Cars that are currently supported already have "smart cruise" and "lane follow". Why then use a third-party self-driving system? [1] https://comma.ai/openpilot#:~:text=Currently%2C%20ope…

Big one, because all those cars require you to touch and move the steering wheel every X seconds. All the ones that let you go hands free cost a subscription of around $500 a year (Ford BlueCruise, GM SuperCruise). And even those only let you use hands free mode on pre-mapped roads, typically only interstates.

Becasue most cars with lane follow still lose lock on the lane when the lines are hard to see (rains, snow, etc) or missing due to exists and other things.

Becasue most cars with lane follow fail to keep well when the turn gets too sharp.

Comma.ai lets you go completely hands free with no wheel nags. It also works just fine when there are no lane lines or poorly visible lines. It also supports lane change by signaling, and then nudging the wheel when it's clear to move.

There is also an experimental mode which stops and goes at stop signs and stop lights.

If the driver monitoring camera in the comma detects you fell asleep or something, it will slow the car down and pull over. All the stock lane keep that I have used in cars, if you fail to nudge the wheel they just disengage and you keep going at full speed in a straight line...

Then we delve into OpenPilot forks like SunnyPilot that let you do things like decouple gas/break control from steering control, so you can control the gas/brake yourself and let comma just always steer for you. Comma can also steer more aggressively in turns than any lane keep I have seen, and when it can't you will see the limit being reached on the little display so you know you will need to help out on that tight curve.

Experimental mode isn't the best all the time, and SunnyPilot allows hybrid mode which uses regular mode and dynamically switches to experimental mode for stop signs and stop lights.

With SunnyPilot it can even read your car's blind spot monitors to automatically make the lane change hen clear without you having to nudge the wheel.

Some have been playing with concepts of auto navigation too where the car will take exits and turn through intersections for you.

The comma.ai devices have 10W of compute power and the current driving models only use 1W, so there is room to scale to better models with teh current comma devices. There is also talk of supporting more cameras for side views and external GPUs addons with 100W compute for potential FSD level models.

Some cars it does not support because nobody has been interested in testing it out. Some cars will never be supported because they are using an encrypted CANBUS. The list of cars on that list goes up every year. Eventually no current models will be supportable.

They’re adding new models all the time

That's covered by:

> Some cars it does not support because nobody has been interested in testing it out.

The issue is that the percentage of new cars that could be supported drops as more and more starts encrypting the CAN bus.

there is also sunnypilot, which is a fork of openpilot, and supports more behaviors and cars: https://github.com/sunnypilot/sunnypilot

What's different? From the README I only get that it's trying to match comma's safety as closely as possible - whatever that means

Ability to decouple gas/brake control from steering, so you can control gas/brake yourself and let comma steer at all times. With OpenPilot, when you touch the gas/brake, the steering also stops.

Ability for the comma to read your car's blind spot monitors and automatically change lanes without you having to nudge the wheel.

Ability to use dynamic mode which dynamically switches between chill mode and experimental mode, so you get the best of both worlds.

Ability to fine tune many settings related to gas/brake and steering sensitivity and control that you can't play with in OpenPilot.

That's the main differences i'm aware of, but there are more.

This looks neat, does it require anything specific to work? What if certain sensors are not available in some geographies. Probably a dumb question

No it doesn't need any sensors. Just needs your car to be on the compatible list.

It plugs in-line with the plug behind your rear view mirror and you pick the vehicle model to receive the correct adapter plug with your unit.

> 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…

Everyone that I have heard from who uses one say that it reduces the monotonous mental load and frees up their brain to focus more on being aware of other drivers and what's happening on the road, rather than worrying about their speed and exact steering.

People report being more alert and more aware of things about to go wrong.
