I don't think ANPR is involved with catching VED evaders - as you must
either have VED or SORN the vehicle, any vehicle that is un-SORNed and
has no current VED is guilty - it does not have to "be caught on the
public road" like the old days...

THough ANPR will catch those who have declared SORN, but use the car on
the roads anyway, which amounts to evading VED.
