i go to their website comma.ai and for the life of me cannot figure out what this is and what they are asking $2000 from me for. "Chill driving"?? Maybe a bit of explanation would help? or is it even active anymore?

I think the tricky part for them is that the hardware and the software need to be marketed differently in order for this to be legal. Out of the box, the comma 3 only functions as a dash cam. You need to personally load openpilot onto it. I guess it's not possible (or wise) to sell a self driving kit currently, but selling a dash cam that just so happens to work really well with openpilot is.

I'm surprised the law's developed enough for that, I'd think it would be on the (non-)driver either way.

The better option to understand how comma's openpilot works is to go to youtube and look up openpilot videos in action.

What they are selling is an ARM board + cameras + CAN bus adapters for various vehicles. The stock software engages lane centering and longitudinal (gas/brake IF supported) and will keep the car lane centered.

For highway driving, it's a huge quality of life improvement.
