I have the original Comma 3 in my car (2019 Acura RDX), and it's pretty game-changing for long drives. The car already has adaptive cruise control and lane-keep-assist, but you need to keep your hands on the wheel. With the Comma, I can set it up on most of the roads I drive (local or highway) and it'll keep me going at the desired speed in the center of the lane (up to a certain max turning torque, which is a limitation on the Acura LKAS system - if you're in the Bay Area, it handles 101 just fine but will struggle on the 280).
I've logged about 3k miles of autonomous driving at this point and wouldn't hesitate to recommend it if your car supports it, with the understanding that it's a limited system and you still have to pay attention the entire time. Unfortunately, it seems like a lot of the newer cars have tighter security around CAN bus communication, so it may not be easy for Comma to continue to do their thing.
- SparkyMcUnicorn 3y agoIt's also notable to point out that OpenPilot is way smoother/better than stock LKAS (and otherwise), and getting better with each release (based on personal experience in Toyota and Honda/Acura cars).
- stavros 3y agoIs there any reason for CAN bus security, other than preventing people from modding their cars?
- TylerE 3y agoI'd imagine the anti-tampering clause (it's a felony!) of the Clean Air Act is one reason.
- fragmede 3y agoThe wiring for the CAN bus can be made to be accessible from the outside of the car with a bit of force, which means that's all a thief needs to do to steal your car. Yank a headlight out until the wiring harness comes with it, making the CAN bus accessible, install the car stealing modchip onto the bus, unlock the doors, get inside, start the engine, and drive off. https://www.autoblog.com/amp/2023/04/18/vehicle-headlight-can-bus-injection-theft-method-update/ https://www.autoblog.com/amp/2023/04/18/vehicle-headlight-ca...
- oritsnile 3y agoThere is a new unece regulation, requiring strong temper protection, which means at least CAN authentication. https://unece.org/sustainable-development/press/un-regulations-cybersecurity-and-software-updates-pave-way-mass-roll https://unece.org/sustainable-development/press/un-regulatio...
