> No reason self-driving technology should be bundled with a car

Aftermarket self-driving is inherently a compromise.

OEMs can design the car for their self-driving system. They can place sensors in the right places, size the actuators appropriately, and integrate vehicle dynamics data into the system.

OEMs can also properly safely test the entire system, operating as a unit, as it would operate on the road.

OEMs also leverage economies of scale to make the best technologies available at reasonable prices. Automaker net profit is on the order of 10%, and their scale is massive. You're getting a lot of bang for your buck.

Aftermarket systems are inherently a compromise. They're limited to whatever sensors can be easily mounted in the aftermarket device. The device is only mounted where convenient. The device can't take advantage of vehicle-specific sensors or actuators or vehicle dynamics data because they need to keep it generic.

And most importantly, aftermarket self-driving device manufacturers obviously aren't safety testing the device in combination with every single car on the road. They expect their users to just sort of wing it and see how it goes.

I think it's cool that Comma is working on this, but it's not going to replace OEM solutions any time soon.

> Look at consumer reports for a comprehensive review [0] (comma.ai was #1 in lane assist, above even tesla).

The report shows Tesla's system was more capable and performed better. Comma tied with 3 other manufacturers for performance.

The advantage of the Comma system was supposedly in the fact that it keeps drivers the most engaged. Kudos to Comma for that, but it's not exactly accurate to say that Comma's lane assist performance beats Tesla.
