I know there have already been threads discussing this but I thought I'd create a new one since it's been a while. Here's my review of openpilot and the comma three.
(Openpilot)
comma.ai recently released their comma three device, which you can install and run openpilot on. Compared to the previous comma two device, the difference is mainly in hardware thus far, with the new wide & narrow front-facing cameras and wide-angle driver facing camera. The device is no longer built using a phone but is rather built on "custom hardware". It feels much more refined compared to the comma two.
The comma three is currently limited by data, meaning that it basically performs the same as the comma two (albeit the higher cost), but as comma collects more data from comma three users, its functionality *should overtake the comma two.
My personal experience with the device has been great. I ordered a comma two myself but had returned it due to the release of the comma three. comma has announced software support for the two up until July 2022, however. I have a highway commute every day so it's nice to use openpilot to ease the drive. The biggest selling point for me was the ability to remove the steering wheel nag and have it replaced by the driver monitoring camera. The lateral capabilities of openpilot is also MUCH better than the stock Hyundai LFA.
The stock Hyundai LFA system disengages when a lane marking is not present, and an issue with that is there is no audible alert that notifies the driver that the system has been disengaged, just a flashing green steering wheel icon that turns white. While the actual performance of the stock LFA system works quite well, I find it to randomly disengage at times even with lane markings present, and it feels like the system is constantly correcting itself and the vehicle ends up swaying left and right. openpilot solves this (not 100% but a lot better).
The biggest thing that is lacking from openpilot however, is longitudinal control. On the current-gen Sonata, openpilot can only perform lateral control (steering), but not longitudinal (gas & brakes). The only method to get longitudinal control working is to modify radar wiring or to wait until comma releases a vision-only longitudinal system. The great news is that the Hyundai Sonata is comma's primary development platform, so our cars will be one of the best that operates on openpilot.
openpilot works best on highways still, but the release of a vision long system will hopefully bring a better experience in the city, meaning red light and stop sign detection, and stopped car detection.
Would I recommend the comma three? If you don't use the stock Hyundai driver-assist systems; definitely not. If you are looking at the comma three because it has "self-driving" features, I would still not recommend it just yet due to the lack of longitudinal control. If you're someone who's into tech, is interested in autonomous driving, and want to mess around with openpilot and your car, then I definitely would recommend it. The comma two is still being sold for $1099 (although many users are selling their used comma two for a lot less), or if you don't want to spend much, you can achieve a lot of the same by building your own device using a LeEco phone.
Also I thought I'd mention, I'm not affiliated with comma, just intrigued in what they're doing and am a tech nerd.
Here's a recent drive I have with the comma three, there were situations where I had to brake due to the lack of openpilot long, in which I couldn't trust the Hyundai system to perform properly.
