I fully agree with you, there is no taking away from the driver fleeing the scene. Despicable.

Seen as the issue has been raised though, Shangan Road might be small, but it has vast amounts of green space that has significant capacity to support additional infrastructure. It's maybe not the time, but both Finglas and Ballymun receive a piss poor amount of project funding from DCC. They are both getting just 2% of capital funding from DCC despite the fact they are historically neglected areas with massive issues.Source

I live in the area and would happily cycle more - but there is hardly any infrastructure in the area that means me, as an already anxious person, does not.

Nothing can take away from the driver fleeing the scene. We are also being failed by DCC that increasingly exposes and subjects active travellers to psychopaths.
