For some reason I'm actually skeptical it has actually been found. A cynical reading is they scanned all the places people were ever likely to intentionally stop on that road and found nothing. So harm is just very unlikely, but leaving the item unaccounted for was just really, really bad press. I want to hear more about the sensitivity of this scanning device, particularly when used at this speed, and from someone knowledgeable in the field.
If they really didn't think it was dangerous (or findable) and didn't want bad publicity then they would have just hushed it up in the first place and never gone to the government & press.
"It was initially detected by staff inside a car that was travelling at 70km/h past the capsule."
Would be funny (depending on how weird your sense of humor is) if they found out it wasn't the device they're looking for, but another one that was lost years ago and never reported...
We were looking for capsule 9089, but this one is 6806..."
"Sir, I've got some good news and bad news..."
