A college student made good use of the open source comma.ai system to convert his Honda Civic into a self driving car. This article gives a nice basic overview and explains the features are similar to the early versions of the Tesla autopilot.
I’m a little surprised about the comments late in the article about regulations. I would assume modifying my own car is fine, but it would still be illegal for me to drive without touching the steering wheel. At least at this point.
I will be looking into the comments about the pre-built neo system being sold, as most people aren’t going to have the ability to solder their own system together. I’ll make a separate thread on Neodriven, the company selling it, when I have some time.
