AFAIK Comma.ai is the only open-source company in the self-driving cars space. It is very interesting that they are continuously launching consumer-products with a small team and in a highly competitive space where the other players are quite big.
This does not in any shape or form compete in the self-driving cars space; the thing doesn't have a rear camera! This is basically the "rsync as Dropbox" approach to augmenting your car with a hacky version of automatic cruise control, with a bonus lawsuit should you ever be in a crash significant enough to warrant the attention (think paralysis).
I used the v1 of this device for ~1 year, and since then driving has never felt the same. It was sooo much less annoying to do regular commutes when the device took control for even 90% of the trip. This was true even though I still paid attention to the road and had hands ready to take the wheel.
