Once self-driving cars become widespread, there are going to start being uncomfortable situations in which people die mid-trip, but still arrive at their destination.

I'm pretty sure the car would be able to detect a no longer functioning occupant and notify proper channels.
Cars in Japan can detect alcohol on tour breath and refuse to start, for example..

I stole this not only for Facebook, but also to use in one of our random pic/conversation Slack channels at work.
It aids in bleeding air from the system during filling. This is why, when the thermostat is installed in a sideways orientation (eg: all 1.8 NA / NBs), the thermostat is oriented such that the "jiggle pin" (Mazda's words, not mine) is at the top.
Also, just as a point of clarity, the picture you posted shows a bypass thermostat, which is not the type used in the Miata engine. (The difference is the plate at the bottom.)
If it was a hole, it would pass water when the engine was running. This would allow water to bypass the thermostat and flow through the radiator before running-temp had been reached. This would delay warmup.
If you inspect the design of the jiggle pin, you will find that it sits open, and thus allows air (and water) to pass though when the engine is not running and pressure on both sides of the plate is equal. But when the engine is running, and a pressure differential (and, thus, flow) exists across the two sides of the thermostat, the pin is forced into a position which plugs the hole and prevents water from bypassing the thermostat.

I think by design thermostats that are remote mounted like the FM reroute have a hole to allow a tiny bit of fluid past. This allows the hot stuff reach the thermostat. IMO, not the best design.

Production employee comes back to the shop and grabs an extension cord without saying a word. He speaks up and says "i'm sorry". "What for?" I ask. He says "my tether is dying and im not close enough to a plug to keep working".
That's why I don't like re-routes that mount the thermostat in a remote housing, seperate from the head.
There seem to be a lot of jobs in which you are expected to be sober at all times while on duty.
Surgeon, police officer, airline pilot, etc.
That must suck.
US flag merchant ships are dry. Most companies don't want you drinking even when you are ashore (very stringent requirements) because of liability concerns. Hell, when I worked for Shell on foreign flagged LNG tankers the Captain and Chief Engineer weren't ever allowed to go ashore. Basically once I joined the ship I was there until I flew home for vacation. That sucked.
