They should do away with the test. We never needed it in my day and we didn't have Google Maps back then, often no more than a lamppost number to go on. If the African/Afghani/Pakistani/etc lads can find their way here they can find their way round Dublin.
The test merely serves as an artificial barrier to entry. As Watty recently pointed out men had to invest in the trade back before entry liberalisation. These days most of us are driving virtually free cars that cost virtually noting to run under plates we got over 26 years ago for IR£5,000. NTA should ban the private rental of taxi plates and issue annual taxi plates at a cost of at least €15,240/year with taxi vehicles restricted to EVs under 3yo and hackney plates available at lower rates for older/FF cars.
