The problem is, most of the industry has spent the last decade adding neat features and trying to improve their reliability...without much practical thought as to increasing controllability (in terms of accident avoidance) in the inevitability of a component failure.

Controllability has basically been shortcut by keeping a driver behind the wheel. We've done pretty significant testing - regularly hauling freight on the highway while in self-driving, no-one behind the wheel in super unstructured environments, dealing with extreme edge cases w/o intervention.

The big technical accomplishment that we're showing here, is that our system is controllable in the inevitable case of failure...without using a physically-present human as a crutch.
