I just heard about Neodriven and it looks like they are taking off exactly where Comma.ai left off. They are using the comma open source software and providing hardware that will allow compatible vehicles to become self driving. They claim the installation only takes 5 minutes by replacing the rear view mirror and connecting one plug.
Interestingly, the price was listed as $1499 or 1 bitcoin yesterday (bitcoin value around $1150) but today the price is down to $999.
I’ll have to do some more digging around, but at this point I could only find a little information about the company. The only employee I could find does not look to be a tech person.
