Just putting it out there Merc .There seems to be a plan to focus on the lack of Prime time cabs but Environmentally putting more cabs on the road at prime time blocking up bus lanes would be counter productive .We probably have to many cabs the Department of transport should be promoting walking ,cycling bus use ,Luas ,Dart and not adding to congestion or emissions with adding more taxies .The best way to increase the efficiency of public transport is to introduce a congestion charge that will encourage more use of public transport and free up roadspace which will increase the efficiency of the existing taxi fleet .Adding more cars to already congested streets to satisfy a small peak time demand seems counter intuitive especially considering our commitments to a cleaner environment .
