That's good to know, some useful context:

tldr: It's going to take a while

The search area is immense. People (even locals) fail to understand the incredibly vast distances. Sure, you can think up a comparison from your own context of a few hundred kms... but does your example have nothing, and I mean, literally nothing manmade but the road infrastructure itself in the proximity of the horizon for sometimes hundreds of kms? Few places do. In more remote places than this, say in the Kimberly, you might as well be on the moon. There's nothing out there to support you or resupply you; you always have to think about that ahead of time.

It's the middle of summer here, we are approaching our hottest month (February). Pavement, being a heat island, makes working alongside or on it a slow process. Exposure and heat stroke are real risks.

On the upside, the roads are sealed, and in relatively good condition and well designed when compared to say much of the US or the poorer parts of Europe but the odds that it falls into a crack or pothole will scale with the distance. A vehicle-mounted detector makes obvious sense but could be costly. However, as we know, especially at these temperatures, roads are slow moving rivers. It might even become embedded if it did indeed land on the surface. In which case it sounds like we may never find it.

Assuming it's most likely in the literal middle of nowhere. The risk of a member of the public coming into to direct physical contact would be highly unlikely. There are sections of road that haven't had human feet walk on them since they were last poured. But that introduces an interesting problem. What happens next time maintenance replace that section? Do crews need to be wary of digging it up, possibly aresolising it in the process? Maintenance is probably the most likely human contact scenario. Does every safety management plan now include the incredibly remote chance of finding it?

> US or the poorer parts of Europe

Sorry to nitpick, but I've driven across the USA many times and I've never had much to complain about with regards to our roads (outside of Ohio, fuck that state). Doubly so when comparing our road infrastructure to poorer countries.

I've driven across the country 4 times now, and lived in all four corners plus the middle (New England, Georgia, California, Washington, plus Minnesota/Iowa). In a cold weather state the roads tend to get rough because of the winters. Roads are expensive to maintain there. Never had any trouble at all in Texas or Arizona. Lots of trouble in California, though, and the Dakotas can be rough outside of I90 and I94. Not a function of negligence or anything in the Dakotas, it's just cold.
The Netherlands is a poorer country with about two thirds the GDP per Capita of the US. Here in Berkeley I see many potholes. I've never seen one there. And that's before we get into the increased road safety.
Please check out Michigan - I can only speak for the Ann Arbor area - but wow, compared to British Columbia (which has almost identical issues with salt, snow, freezing) - the roads there are really beaten up.

They even have a saying - there are two seasons in Michigan, Winter and Road Construction.

Around San Francisco they’re noticeably worse than the well maintained parts of Europe.
Agreed, as someone who has lived in multiple western countries and US states...the roads around the bay area are horrendous. I try to drive in the fast lane to avoid the damage done to the slow lane by trucks.
I really don't follow this narrative. Yes it's hot and remote and it's a 1400 km road. All of those things are clear. It's still very easy to put sensitive detectors inside a vehicle and drive along the road. These are uncommon and fairly expensive devices but there are plenty of them around. If the source is on or near the road it will be found that way pretty easily.
You're correct not to.

The road is mostly sealed (Perth (State Capital City) -> Mt Newman (Big hub town in Pilbarra)) with a short tail end road of maybe 50 km to the site in question that'll be probably graded gravel - rough, bumpy, but essentially flat.

With five days gone it's already been flown and driven .. at this stage they're either looking at trace signal and indications the slug has gone well off route in a truck tyre OR doubling back to see if any site workers flying out pilfered it as a souvenir and flew out to Thailand for a holiday since.

Also: the Kimberley is not like the moon.

Another Nit - I don't think that the odds it falls into a crack or pothole scales with the distance - it's a fixed probability based on the condition of the road, and not its length.
