>There's a long list of things Autopilot can do that Openpilot will never be able to do with existing hardware.
Such as what? Autopilot is completely vision/radar based as well. Sure it has a few more cameras for a greater margin of safety, but its' effective capabilities are the exact same. It's still completely reliant on tracking lane lines, the user has to disengage at stop lights, and it can't make 90 degree city street turns. The only real difference I can see is automatic lane switching, which is available in some Openpilot forks.
Such as Navigate on Autopilot(freeway interchanges and exits), speed based lane changing, merging, object detection. There are 8 cameras, 12 ultrasonic sensors, and a radar. They are not the same.
