Under the circumstances, I'd accept just slowly rolling to a stop with the hazard lights on. People behind the car will hate it, but probably no one will die.
Sadly, I can still imagine someone crashing into a static car on the highway. I can imagine normal-speed continuation, mid-lane stopping, and attempting to navigate to the side of the road all seem to have some pretty heavy risks. I do wonder if a low-speed continuation would be in any way suitable.
