With regard to the national car test there are some anomalies, one of which I would like to raise. If one acquires, say, a ten year old car and the previous owner has not had it tested and you as a good citizen have it tested, the certificate covers only the remaining amount of time from the time when it should have been tested. That is idiotic. One could get a certificate that lasts only three months, when it should last two years from the date of the test. The miscreant, who is the previous owner, should suffer any penalty.
