I have been wondering how the software works, I presume it scans the area of the front and rear of the vehicle looking for something close enough to the accepted font to read it.
Supposing one had more than one plate, now the second plate need not be a false numberplate, just something obvios enough to plod to be a sign or show plate but using the accepted font, how would the software react ?
The law with regard to plates seems to be a bit of an Ass anyway, so far as I know it is not illegal to buy plates abroad without producing a V5C and whilst it might technically be an offence to fit them as new plates, if I am going for the historic look who is going to tell they are not originals, or care, so long as the numbers are legible and close enough.
