The pdf is pretty helpful! Outside of total system failure, it will try to find a shoulder, and if it can't do that it will gradually come to a stop inside its lane.

In such an instance, “controlled stop” means that the system has the capability to control both steering and braking, so that the system can continue to ensure it is not leaving the lane as it brakesand is not hitting objects in the lane ahead. “Immediate stop” is the final fallback mechanism for the extremely improbable occurrence that everything in the system is failing.

That was the paragraph I found interesting. It seems to me in the worst case scenario from what I can tell it just slams the brakes and hopes for the best. It would be interesting to hear a response of what the truck would do in a jamming situation. I assume since it would not lose it cameras and other sensors it would slow down and pull over.

Sounds like the beginning of the next reboot of Fast and the Furious in ten years.

I'd trust a stupid autonomous system to be safer than a driver who loses consciousness during one of those situations. You just need to make sure that the system doesn't break down completely more often than human drivers have a heart attack at the wheel.

I feel like losing cell signal is more common than having a heart attack.

I feel there are good mitigating options here:

- they could use vehicle-mounted transceivers with much better antennas

- they could use redundant transceivers on different networks

- they could map out routes with best signal. Remember this is last mile only, so it's not a huge area. Instead of going the shortest way a la Waze, optimize the route for best signal.

It is not just loosing cell signal completely, but even smaller latency increase can make teleoperation much less reliable.

Should it be performing turns in front of traffic coming that doesn't have time to stop?

Apart from being more in the way, how does this differ from having to stop within a lane?

The article says its automated driving on the highway.
