IN A wet, cold week when drivers at one bus station decided to strike, leaving thousands to walk to work, the CSO statistics showing car usage rising sharply, will come as little surprise.
People use their cars because they have no option.
They use their cars because it is easier to sit in a traffic jam than wait for a bus that may never come, or a train that, when it does arrive, may well be full, leaving commuters stranded.
They use their cars because, even though they may be late, it is the only way they can guarantee actually getting to their destination.
They use their cars because property price inflation has forced hundreds of thousands to move to a "commuter county" to afford a home. But of course, there were (and still are) insufficient bus or train services to help them to get to the centre of Dublin where they still work.
They use their cars because, although the Luas has been a huge success, its capacity can carry only a small fraction of those commuting into Dublin.
They use their cars because in many outer suburbs, local councils now charge for parking near Dart and Luas stops, making the concept of 'Park and Ride' more expensive than taking the car.
They use their cars because there is still no integrated ticketing, making it almost impossible to switch methods of public transport easily and speedily.
They use their cars because there are now so many cars on the roads, it is no longer safe for children either to walk or cycle to school.
They know Transport 21 is full of great plans (albeit with 12 projects behind schedule) for city centre interconnectors, undergrounds, a Luas link, a train to the airport, more buses, more bus lanes, integrated ticketingf you name it, it's there.
It's just not here now, when we need it, so we can stop using our cars.
