Dubliners reclaimed part of the city centre yesterday as they celebrated Car Free Day.
Organisers deemed it a "success", but said there are no plans as yet to extend the scheme. This is despite complaints the city was not going far enough.
Families and tourists turned out to revel in the atmosphere of a pedestrianised College Green yesterday with a BMX stunt show, children's yoga, walking tours and a cycling tour, all in full swing.
But some took to Twitter to complain Dublin wasn't showing the same example as Brussels and London. In London Tower Bridge was closed for a mass yoga session while more than 27km of streets were shut to cars.
"Brussels closed the entire city to cars and make all public transport free for car day. Dublin closed one street for a couple of hundred metres," one Twitter user said.
"We think it went really well, 21,000 attended. There was a steady stream of people all day," said Antonia Martin, from Dublin City Council.
When asked about the size of the event in comparison to other cities, she said: "We have to review and debrief how it went from all aspects, from activity on the street and traffic flow.
"The road closure space was the same as during the summer and we are looking at this from a safety point of view and the impact on buses and other transportation coming into the city, to try to have the right balance."
