WTF is up with the replies?
This seems perfectly legit to me.

K, this guy is a legal 70mph, the police are a few miles behind, see him in the distance speed up to over 80mph to catch up, signalling for him to pull over, and they both slow down. So Mr Napoleon is doing a legal 70mph up until the point where he is signalled to be pulled over, where he and the police both slow down.

So, the police (superficially) seem to have made the assumption that since they had to go fast to catch up to him (ie accelerate in the same way you might have to run to catch up someone who is walking), he must have been going fast.

But when I explain it, it has no humour at all instead of the slight grin it gave me on the initial reading.

Yet, I can't help feeling that fatigue has rendered me victim to some trans-modernist irony.
