Quick bit of feedback for any Comma employees lurking: It took me a very long time to realize that this was a self-driving solution for existing vehicles. The hero just says "Driven over 6 million miles" and then a "Buy Now". When I scrolled down and looked at the product and read: > We’ve added an infrared camera to provide 24/7 driver monitoring, an integrated panda, a custom cooling solution, and an OBD-C port wit…

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?
Actually it's a horrible thing, think of it, a terrorist can buy one of these cars, install rasperrypi with internet access through mobile data, then they can terrorize the whole town by running people over without being caught or killed
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…
Great perspective. Why isn't SDC software held to the same regard as Boeing? The safety framework is the same.

Came here to say something similar. I briefly thought it might have been a self-driving add-on because of this bit: >The comma two does not ship preloaded with software capable of controlling your car. Open source software can be installed separately. But then I figured that if it actually did that, they'd be screaming about it, not talking about how you can watch your drives. Kind of hilarious.
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…
Comma and Tesla do driver assist, neither are self-driving.

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.
OpenPilot generates all of the control messages to send to the vehicle based off of feedback from the cars sensors and it's own camera. it has rate limits for all control messages it generates so that it can't jerk the steering wheel or slam on the brakes (as of now it leaves Collision Avoidance up to the stock system)
Steering limits: https://github.com/commaai/openpilot/blob/a2ae18d1dbd1e59c38...
Accel/Decel limits: https://github.com/commaai/openpilot/blob/a2ae18d1dbd1e59c38...
These control messages are then passed to the Panda over USB. Panda is a microcontroller that converts the control messages into CAN messages that the vehicle can understand. The Panda has the same rate limits checks hardcoded into the firmware and it will reject any control messages that are outside the limits
Panda Safety code: https://github.com/commaai/openpilot/blob/a2ae18d1dbd1e59c38...
Finally, because Panda is sending the same CAN messages as the stock ADAS system, whatever safety mechanisms the OEM implemented apply to OpenPilot as well. Most cars have some form of torque caps and some form of rate limiting baked into the EPS firmware.

Someone should tell Tesla because they use that term all over their site, marketing, and tweets.

Geohot is quite abrasive.
