Post em car sharing in Ireland ---- (rented cars and private lifts)

I am travelling from Gorey (I'll pass through Wexford and Waterford probably) to Cork on theese dates, I am not in a hurry so I can wait for someone if that suits.

I am from Spain and I use use a lot "Blablacar", an app to share trips and costs. It's so popular there I love driving people or sitting down as copilot to share a trip....

I would like to do the same for this trip here in Ireland, but I find really difficult to get this kind of things here..

Thank you very much I hope your replies!!
