Makes Comma 4 a much better product. Starts, stops, lane change etc.
I bought the Comma 4. I loved what it did for helping with lane assist. I didn't have to keep grabbing the wheel. I wanted longitudinal assist with starting and stopping. Theis did the trick! It seem to take forever to arrive, but it was well worth the wait. I installed the beta Sunnypilot software and had to make some tweets. But now I'm absolutely loving it. I feel I can wait for a while to purchase a new vehicle. This is really a game changer! Oh, and customer support was very helpful when i didn't see updates with the shipping!

Works excellent.
For other buyers....
After you install this, unplug USB from your comma.
Plug USB back in and now you can turn on experimental mode.
