The argument for a road fund cash cow is made even thinner by this process....
The tax disk was always in place and argued by successful ministers of transport as an annual check that you had an MOT and insurance, this worked for traffic wardens, bobies on the beat as well as traffic rats. The national database now maintains up to dat info regarding MOT, insurance and tax, ANPR enforces this on every major road and many other places besides. Most patrol cars and unmarked are now ANPR equiped so there is no need for annual road tax. Realistically absorbing it into fuel duty will hurt innitially but it will cut down dramatically on administration!
Now what do we do about all the unisured, MOT'd or tax paying Eastern European motors outstaying their alloted time, avoiding fines and in a darn right dangerous condition???
