Well, I think Comma gives a tough competition to Tesla given the features which it offers when compared to AutoPilot of Tesla. There are lot of masses who still cannot afford a Tesla( and their $7K package for full self driving cars). Imagine all of (atleast 20 %) Comma AI and Openpilot supported cars actually using this hardware and software in the next 6 months which is way more than the number of Teslas in the market. Also, it avoids the necessity of owning a Tesla. Coming to safety, I believe Openpiot with Comma makes a driver a better and safe driver with driver being attentive. I wouldn't drive a Tesla without being attentive even it offers Level 4 autonomy (because we always need to have an eye on the road and pitch-in when needed as this involves people's lives and there is no single system in the market which is 100% perfect).
