Comma.ai represents a strange attitude towards life in which you try to turn hard, serious problems (like self-driving), into trivial problems (write some Python and run it on Android phones and plug it into your car!) and try get away with it. It only has a chance of working if you are cool enough in SV such as geohot. I interviewed there once and it was extremely off-putting how clear their demand for fast progress…

And this time it's people what they're moving :P

I find driving much less fatiguing when using my Eon (the previous iteration of this product). Taking yourself out of the feedback loop of constantly adjusting steering (and gas if in traffic) makes the experience much more relaxing even though you still have to pay full attention. In my experience, OpenPilot is really rock solid in normal highway driving scenarios and there isn't anything stressful about using it. A…

Thanks for the perspective. Do you happen to know what the hardware safety is like? Just curious.

There’s the self driving code and native layers that runs on a bog standard Android phone, then an Arduino like microcontroller handles interfacing which is more or less realtime. Malformed, illegal or out of range commands would be trimmed out if occurs.

They also has a narrower than commonly used limits and that is reportedly insufficient for tighter curves on some highways but are done so in good faith I guess.

If there is anything about Comma.ai that I have seen beyond the hype of self-driving cars, I see this as substance, unlike the rest of them AI self-driving cars (Except Tesla). The idea to turn your existing car into self-driving rather than spending $$$ on a new one makes sense for those saving money. Comma.ai is for cars what Linux is for PCs, meaning that you use open-source software and a hardware kit to make you…

>The idea to turn your existing car into self-driving rather than spending $$$ on a new one makes sense for those saving money. You sure this is where you want to save money on a self-driving system? God forbid there's an accident, what then? There's no big company you can point at for recourse and I guarantee that Comma.ai isn't going to stand by and accepted responsibility - their website makes it clear that the de…

Why is it dangerous? Self driving software instances costs a lot to develop but nothing to manufacture, and the cost cannot be used as an indicator of its safety or sophistication, at all.

Let's say I order this stuff and flash the firmware of my car. If there was a bug in comma ai program (like jerking the driving wheel and slam my car in the guard rail without giving me time to react) I guess I am liable? That sounds like a bad idea.

Yes and yes, but the alternative is you never enjoy self driving and the potential it has to reduce fatalities for the rest of your life.

It’s a trolley problem, this thing WILL KILL, the question is how more/less often compared to humans.

Geohot is quite abrasive.

I’ve seen worse characters (Torvalds) but yet they are loved by the ‘community’ despite their behaviour.

> but it’s still operating within the bounds of the factory electronic steering That's Comma AI's approach. Their hardware spoofs the stock computer so it can send commands to the car's active safety systems. So there are some stock limitations, like the steering torque, that openpilot doesn't bypass.

This doesn't address the fundamental issue: a car is being controlled by an untested and unregulated system on public roads.

Secondly, the models are not open source, and even if they were looking at them tells them nothing about the quality of the product.

Unless something changed I missed, the part I emphasized is not true. There’s binary blobs in the source code that last I heard would not be released.

Wait wait wait, are you telling me I can actuate the brakes and gas and turn the steering wheel via the CAN bus? So I can realize my dream of turning my car into an RC car just with a Raspberry Pi and a $4 dongle? That is the best news of the year! Which cars have these sorts of actuators? How can I see if mine does?

Yup! https://github.com/commaai/openpilot-tools/raw/master/steer.... If your car is in this list: https://github.com/commaai/openpilot#supported-cars then it definitely works and you can use these tools to control it https://github.com/commaai/openpilot-tools If it's not in that list then the rough heuristic is whether or not your car has some sort of existing driver assist features e.g. Adaptive Cruise Control, Lane…

I agree, both cell phone drivers and people with unlicensed, untested, unregulated homebrew self-driving setups are dangers to everyone around them.

As are people with 15 year old rusted hoopties, drivers who had a fight with their significant other, disagreement with a colleague or whose sports team just lost, drivers who slept poorly the last few nights, drivers who are ill and taking cold medicine, cars with lamps out, worn tires, worn ball joints, bad shocks, no ABS, no vehicle stability control, etc. I’m okay with enthusiasts repairing and modifying their ca…

I agree, driving is dangerous. Why is the response to add another dangerous hazard? This argument is ridiculous.
