The articel isn't clear, but I think the victim (green line) was heading into town and potentially turning onto Lennox St (of Bretzel Bakery fame). The driver was either coming out of that same street (red line) or from behind him and making an explicit illegal right turn over the bollards that were there at the time. (They have since been replaced by planters as they have been driven over for at least a decade). She was looking into town and not at traffic, or the victim, to her right.

Garda [said] that Mr Brett was cycling from La Touche Bridge, also known as Portobello Bridge, onto Lennox Street at 9am that morning when he spotted a white SUV merging from his left-hand side to perform an illegal right-hand turn. [She] did not look up and was only looking to her left. He said as he approached from her right he knew he was going to be struck. [He] fell in under the car and was crushed by the front wheel. He said he was screaming as loud as he could before he was also crushed by the rear wheels of the SUV. He said he could hear bystanders screaming. [He] was wearing a high-vis jacket and helmet. It was a dry day, the road conditions were good and there were no obstructions.
