Nerd snipe: given a compass and dropped in a random location what is the best strategy (based on direction assuming no clues from terrain) of finding a road. E.g. strategy might be 1000 steps south then 1000 east, repeat.

Go find water and then try to follow where it flows. Look at the scenery and try to determine whether you're in a valley or on a plateau or in the mountains.
Compasses are pretty useless without a map or a terrestrial view of some sort, as all you can do with them is shoot a bearing relative to magnetic north, or if your compass includes a declination adjustment a bearing to true north, provided you know the declination beforehand. It's often printed on topographical maps for this reason.
If you're on top of something then you can use the compass to get somewhere you can do dead reckoning. Usually there's little landmarks every 10 or 20 feet that you can stay on a bearing to. But if you can't see any topography from where you're at you'll have to infer it somehow. So another strategy might be to head uphill if you can ascertain there will be some kind of view there.
A lot of what you'd do depends on the terrain you find yourself in.
Honestly I’d just walk downhill. Most human settlements are on rivers, most roads take the lowest passes. At night, I’d just walk in the direction of the sky that’s glowing the most.
Melville (roughly) agrees -- from the first chapter of Moby-Dick:
---
Once more. Say you are in the country; in some high land of lakes. Take almost any path you please, and ten to one it carries you down in a dale, and leaves you there by a pool in the stream. There is magic in it. Let the most absent-minded of men be plunged in his deepest reveries—stand that man on his legs, set his feet a-going, and he will infallibly lead you to water, if water there be in all that region. Should you ever be athirst in the great American desert, try this experiment, if your caravan happen to be supplied with a metaphysical professor. Yes, as every one knows, meditation and water are wedded for ever.
Specific to the U.S., assuming no terrain clues - go NW, SE, SW, or NE, as most roads in the U.S. go N, S, E or W - mitigates the possibility of parallel tracking.
The latter - pick a direction, walk in a straight line.
Weather is the only likely natural hazard outside polar bear country (and to a lesser extent grizzly country because grizzlies are less likely to see you as food). And if you are in polar bear country weather is extreme.
But as the saying goes “there is no bad weather just poor clothing choices.”
Sorry for the huge response to your passing comment but:
Not really. Statistically, the things that most often kill people lost in the wilderness are exposure and following that, accidents that outright kill or weaken the body's ability to deal with the weather and thus accelerate exposure effects. You do not need freezing temperatures to die of exposure. Even being exposed to mild cold, but continuously, and particularly if wet or partly submerged in water, will eventually bring your body down to hypothermic temperatures.
Hunger is barely a factor because you can go without food for an exceptionally long time before you weaken severely, let alone die, and though we need water to live quite soon, it's rarely impossible to find unless you're in a very arid place. In either case, if the weather is bad and you're under-dressed, that's what will kill you well before you need to worry about dropping from hunger or even thirst.
As for wild animals, they're your single lowest worry, despite being the things that tend to most scare people about the wilderness (thank our ancient hunter/gatherer instincts for this, since they led to us not immediately fearing things we'd adapted ourselves to handling well, like weather and sources of nutrition, but continuing to fear the things we couldn't easily control, like lurking beasts).
Generally, you'd have to be incredibly unlucky to be the victim of something like a bear or puma attack and forget completely about attacks from any other animal, since they're nearly unheard of.
Just to be clear, with most of the above i'm referring to North America or at least to some sort of northern or southern temperate region that may include deserts, forests, prairies, etc, and not tropical conditions or wildlife.
In tropical conditions, and especially jungles, the calculus changes quite a bit, with exposure being less of a risk (though one can be surprised by unexpected cold, as has happened to me in outright jungles deep inside central America where you wouldn't fucking expect to feel really cold, but holy shit!.) Certain kinds of wildlife also become much more of a danger in tropical places, though with few exceptions, the really problematic ones won't be the big predators. Instead you can genuinely worry about smaller things that sting or bite with venom.
Walking in a spiral pattern (where the layers of the spiral are close enough that if you look toward the center, you can always see the point where you were on the previous layer) will guarantee that you eventually see all points on any given radius.
Keep in mind that tragedy happened all the way back in 1986.
Anyone doing the same kind of work today (bore maintenance in extremely remote Australian desert) likely has a Personal Locator Beacon-which can be used to transmit your location to the authorities in an emergency via satellite. Dramatically increases the odds of being rescued promptly if stranded.
Same time as I was doing similar work in the same area, same time the Pintupi Nine popped up wondering who all these pale people are.
> likely has
Yeah, mostly the case but certainly not all .. had they been available at the time it'd be unlikely that pair would have been given an EPIRB given the run down economic state of the pastoral station then.
If you want an EPIRB success story for those that are routinely well prepared, there's this tale from the Gunbarrel network:
If your employer doesn’t supply one for that sort of work, they need to be reported to the OH&S authorities. That said, you can always bring your own. If it were my kid in that scenario I’d buy one for them.
Another factor: currently satellite-based SMS is becoming increasingly available - I just got a message from Telstra the other day telling me it had been enabled on my service (using Starlink direct-to-cell). In years to come it is going to become ever more mainstream. So even if you don’t have an emergency beacon, so long as you have a sufficiently recent mobile phone…
.. then you're golden and just waiting for some one to pop on out the David Carnegie Road, or out into the Tanami.
Communication is only part of the issue here.
In the above linked recent incident the police when contacted couldn't make it out from Kalgoorlie (despite an initial indication) and handed off to a station owner who was able to make a 600 km+ round trip across a broken road to resupply water.
In a truly life-threatening situation, the emergency authorities can send help by air
If they don’t and someone dies as a result, they are going to have an awful lot of explaining to do at the coronial inquiry, it isn’t going to end well for them
Of course I realise in this 1986 tragedy the coronial findings (whatever they were) seem to have made very little impact - but again, I think standards and expectations today are different from what they were almost 40 years ago
