I have a comma 2 in my accord. I love it, would never go back. There is no comparison between stock and comma. Comma is hands off, stock requires hands on the wheel. Comma is constantly updated, upgraded, and learning. It gets better all the time. Stock is what it is and will never be better in your vehicle or upgraded. Comma has full laneless driving as well. Stop sign and stop light detection rolling out soon (videos already up), better driver attention detection, etc.
It's all of 5 minutes to install, and doesn't hurt stock at all. One click of a cable and your back to stock. It's also money-back guaranteed. Try it, don't like it and send it back.
Not sure why the hostility towards it, it's just leagues better then stock and only getting better every day. Saying it's no different then stock isn't even remotely true. Just my 2 cents from an actual owner and user of the system.
