A wayward car spotted driving down tram tracks on the busy Bourke Street Mall during peak hour has fuelled concerns authorities still haven't found a solution to stop vehicles entering through tram entry points.
The incident on Monday, comes a little over a year after six people died when Dimitrious Gargasoulas allegedly drove a car into the busy CBD mall and mowed down dozens of pedestrians on the afternoon of January 20, 2017.
One witness said he was standing on the corner of Bourke and Elizabeth streets waiting to cross the road on Monday afternoon when he saw the car accidentally turn the wrong way into Bourke Street and drive down the tram tracks.
"I looked up and [then] down in the mall came a black Toyota," witness Dallas told radio station 3AW on Tuesday.
"I looked again at it and I thought 'that must be a police car' [but] as it got closer I saw it was just two normal people sitting in there with the P plates on. The question is how did they get in there? There was no police, there was no one."
The first of Melbourne's permanent stainless-steel bollards were installed in Bourke Street Mall in November last year, as a part of a new $10 million CBD security upgrade to protect the city from another vehicular attack.
In December last year, safety fears were heightened again when Saeed Noori, 32, allegedly drove a car into crowds at a busy Melbourne intersection killing an elderly grandfather and injuring 17 others.
Mr Noori was sitting about four cars back from traffic lights travelling west on Flinders Street before he allegedly drove up on the tram tracks and accelerated into pedestrians.
Victoria Police Minister Lisa Neville said on Tuesday while there was no way to completely eliminate risk, the state government was doing everything it could to keep pedestrians safe.
Ms Neville said it was evident from images captured of the incident that it was an inexperienced driver who had accidentally found themselves driving tram tracks near the Bourke Street mall.
She said the government was investigating ways to reduce the number of vehicles, including delivery vans, and added that mechanical bollards remained on the agenda.
“The security group that’s working on the bollard system is finalising on their recommendation on what we do on the tram tracks,” Ms Neville told 3AW.
“The idea would be to have some block on those tram tracks that trams could initiate and other emergency vehicles.”
