It doesn't have to be realtime. Camera control centres send daily

centres detect and investigate cars with plates on the watch list.

Right and a daily update to the database helps in the identification
of cloned plates how?

I can drive from the UK to Italy in a day, so there are few corners of
the UK that are unreachable in a day. What use is a daily update when
both suspect and real vehicles can move faster than the updates are
created?

The info includes the time and location each number plate was seen.

Precisely. I thought this was so obvious i didn't need to mention it; my
apologies.

Indeed it does. And this helps you to determine that the car in question
is the clone? No it doesn't, you still need to do a stop and a document
check.

Indeed, and i never said it didn't. But it does tell you which cars to
check - your list of suspects has a length equal to twice the number of
cloned cars, as opposed to
however-many-tens-of-millions-of-cars-there-are-in-the-UK, which i would
say is an improvement.

As normal. SF has not given this much thought!

I've given it considerable thought.

You're thick, then.

Talking to yourself eh? Very bad sign that.

And a sharp wit to boot!

Perhaps we can compromise: he's thought about it for a long time, but he
hasn't given it a lot of thought.

But this guy's a citizen of urd/uk.tosspot, so this is not surprising.
