Did you not find an answer yourself; i.e. 'asshole'? Most other anatomical inserts also apply, at least the non-gendered ones.
Does not offend any particular group, except perhaps those with a colostomy.
Still an insult.
The remainder are generally insulting because they imply you're so X that you must be a member of group X. I.e. calling someone brain-dead, an idiot, a moron, slow, the French word for slow etc. You can't call someone stupid without calling them stupid, even in an indirect way.
Edit: Neanderthal and troglodyte might work on the grounds that you're comparing them to extinct species, and of course you could go for inanimate objects e.g. thick as pigshit, as smart as a bag of rocks etc.
Partly this is because there are 2-4 roads in parallel attempting to move the same number of people, or demand is unmet because people can't get to where they want to go when they want to go.
Honestly you're in the 11-15m range in most cases, because you want lineside equipment (signal cabinets, masts, cable routing etc) and ideally a 4WD path for maintenance access.
9m is doable but you don't built an entire system like that unless you really have to. Equally, your roads have hard shoulders and crash barriers.
Usually these systems rely on people getting on/off at different stops, rather than one stop seeing full volume. If it's one stop, chances are it'll look like a terminus station and you'll need several platforms and possibly dual-side boarding to each train. It'll be quite a bit wider than tracks with no station, or a minimalist station.
This is pretty common at major sports arenas.
The same of course applies to other transit options: high-capacity bus stops take up space, and motorway interchanges and especially carparks also take up a lot of space.
50k PPHPD is near the top of what can be easily achieved in a metro with one track per direction, but certainly achievable. 2x4m wide tracks and some space for ancillary equipment and fencing is reasonable.
You get maybe one passenger per two seconds in a car lane, or about 1800 per lane per hour. That implies 28 lanes each way, 55 total, or about 165m assuming 3m lanes (pretty narrow). Seems fair to me.
I'm assuming they moved to HFAs/HFCs for basically the same reasons refrigerants did: still non-toxic, still non-flammable, now no ozone concerns.
If they want to replace them with low-GHG alternatives it starts getting tricky.
Hydrocarbons are great but flammable, and flames inside your lungs seems even more exciting than some propane leaking out of your fridge.
Hydrofluoroolefins (1234yf and 1234ze) are probably about to be banned as PFOA precursors, although Wikipedia says the latter might be introduced in inhalers...
CO2 doesn't liquefy and breathing it in is going to make you feel like you're suffocating.
I'm picking HFCs are going to stick around in medical applications for a while where dust/liquid options aren't feasible.
That or returning to some kind of blower mechanism for ambient air.
Road design is part of it but improving road design only improves 'reasonable' drivers, and things like chicanes, lane narrowing, and speed bumps cause issues for larger commercial vehicles like buses.
Persistent asshole drivers will still drive drunk or drive dementia, run red lights, or go three times the speed a road is built for.
"the systems and environments we place people in" is not just the road. It's the licensing regime, the society that makes having a car necessary even if you can't drive safely or afford to maintain it, and that doesn't mandate effective ongoing training.
The point is that any unsigned image is assumed to be AI generated. You can absolutely strip the metadata or convert it to some other format (there's always the analog hole and it has to become a bitmap to be displayed) but then you've lost the proof you took it.
You'd still need secure key storage hardware and trust roots in the camera like TPMs but every phone has that already...
(This is referring to the 'signed in camera' model)
You also want a weapon you're familiar with and that you can control. In medieval farming communities, chances are everyone's used a pitchfork. Axe less so.
Pitchforks also work better as infantry; they're kind of a mini pike so they're useful in a mass and against horses. Swing an axe in a mob and it'll hit your neighbour.
A good number of bombers got taken out, so two parts is not entirely out of the question.
