"Safely" or "legally" slow down?

It seems that in cases like these there are two possibilities --either the driver is passed out/dead, so you definitely do want to stop as soon as possible, or the driver is a dangerous idiot, as it is in this case, so he also should be stopped quickly, and if he rack up another traffic violation in process, well, serves him right.

Practically speaking, of course, it is not obvious if Tesla is capable of safely navigating to a safe shoulder.
