Probably the same reason people don't use seatbelts in buses, I'm very often the only one wearing a seatbelt when I travel by bus I've seen aftermath videos and photos, I'm not taking my chances
Interesting, I've never seen a bus with seat belts

In my 5 decades of flying regularly (US-based flights), this is made crystal clear by flight attendants and repeated PA announcements.
It needs to be safe and clear by design, not confusing to the point where systematic PA announcements are needed to clarify the fact that "seat belt sign is off" actually means "you should wear your seatbelt".

You can induce multiple Gs when pushing hard enough. Negative Gs and everything and everyone not strapped in flies into the ceiling. Which then must at some point come down. Injuries from first crashing headfirst into the ceiling and then out of control falling back into your chair is a given when you have hundreds of passengers on board. Especially on a Boeing which does not limit the flight envelope like an Airbus…
People have averted hijackings by using sudden movements to whip the hijackers around the cabin: https://en.wikipedia.org/wiki/Federal_Express_Flight_705

The other thing about cars in NH is that insurance is optional. I'm not sure what happens if someone legally driving in NH without liability insurance drives over the border into a neighboring state. I asked a lawyer friend once and he mumbled something about interstate commerce making it legal. I'm not how that debate would go when stopped by a cop in MA and asked to show proof of insurance.
> I'm not sure what happens if someone legally driving in NH without liability insurance ... Wait, you don't need _liability insurance_?!

They should install a gravity switch. A simply contact that uses gravity to either remain normally-open or normally-closed, and then when the opposite is true, automatically flush.
Open question: to what extent does the flush mechanism in airplane toilets rely on the presence of gravity?

This. Clear Air Turbulence can strike at any time, and you - as in your body - can get seriously damaged even with moderate turbulence. Few people have ever seen severe or extreme turbulence, including the flight crews, but that can happen as well.
When I was 5 or 6 years old I was flying-sitting with my dad, as passengers, though he was an airline pilot, when we hit a pocket of "dead" air. Meals and drinks were just served. For what was at least 3-5 seconds all of the meal trays floated up, hovered and then thankfully relatively gently settled back down. My dad estimated we dropped 200 feet or so.

My god could you imagine if this happened when you were in the bathroom?
I'm a worrier about things like these. I always imagined that's why the roof in the bathroom is lower and curved. A lot less room for gaining vertical speed. So you'd be temporarily stuck to the ceiling and perhaps a bit dirtied, but less hurt than getting double struck by first the lockers and then the higher ceiling in the aisle.

Yes it is, didn't Einstein say that gravity and acceleration are indistinguishable
"Zero-g" is different to "zero gravity". https://en.m.wikipedia.org/wiki/Weightlessness
