AFTERMARKET AUTOPILOT: Comma.ai will ship a $999 autonomous driving add-on by the end of this year.

This isn’t a kit that makes your car into a fully self-driving vehicle, [famed iPhone and PlayStation hacker George] Hotz is quick to note, but it is a system that can provide powers equivalent to Tesla’s Autopilot, without requiring that you buy a whole new car. “It’s Mountain View to San Francisco without touching the wheel,” Hotz said. At launch, Comma One will support a small group of specific vehicles, but over time the startup hopes to add compatibility with more models.

Hotz contends that Comma’s key ingredient is “shippability,” a key ingredient he says other companies lack. Automakers and other startups are fond of announcing self-driving car projects (another was announced earlier today, in fact), but Hotz points out that many of these companies don’t even have hardware, let alone products they can sell to consumers.

“It is fully functional. It’s about on par with Tesla Autopilot,” Hotz said. It doesn’t have a lot of sensors as the Comma One relies on built-in car front radars and comes with a camera.
