Don't believe all you read!
They're spacecrafts cunningly disguised as mobile chippies.
There are no wheels cos where they come from they don't need wheels as they don't have roads.
That gizmo on the top - looks like a camera, don't it? Nah, it's the engine - small, compact immensely powerful. I nicked one and fitted it to the roof of a mate's Mini - he scorched off down the road and I've not seen him since! I wouldn't mind, but he owes me a tenner.
The other flattish looking thing on the roof? That's the aircon. unit. It gets a trifle warm when entering the atmosphere, dontcha know.
I think (hope?) that at a pre-determined signal, all these craft around the country shall lift off and hunt down all the illegal immigrunts, ne'er-do-wells, the surly, useless, teenage shop assistants and ........... Man U supporters. Nah, scratch that - anything to do with Man U!
Those of us left - and I know I'll still be here - will be able to live life in this country as we should, but until then, we just have to keep schtum.
Keeping schtum for a while then..............
