Sure, then it would be a refrigerated truck with the fridge turned
off, so it makes no sense to be inspecting all fridge trucks which
are running with their fridge turned off. And by definition those
wont have illegals in them because the heat sensing scanning
would see illegals.

Given their insulation it's unlikely the heat sensors would work.

The few hundred watts from a few people wouldn't make much difference to
the temperature of the whole thing, and there would be no hotspots.

And most non refrigerated bulk loads ad done in containers
now, not non container HGVs.

Part of my commute is on the A14. There are an awful lot of HGVs
carrying a container to or from Felixstowe.
