This is still true except it is probably not that "Plod" are ignoring it, it's that there are not enough of them to deal with the problem like many other offences thanks to Teresa May
You might like to think that but you would be wrong. Numbers of traffic plod have halved but it dates from the intro of the devil's gadget, the gatso, when chief constables took the view that traffic plod could be re-assigned to other duties. In London for example the numbers of traffic plod had fallen by 40% between 1980 and 2000, and have fallen further since then.
