Really geeky question, but what will happen with driving licences / registration plates. Would all scottish drivers need to change plates to a different colour/format to distingish from English/Welsh cars. Would all drivers need to replace their UK licence with a new one?
Eit: and previous...
Hypothetically if Scotland gained independence and then wanted back in, say 10 years down the line is this possible? On the same note if the no vote wins when would the next referendum be held (ie when is the earliest possible next date?)
