Last night: Black Leixlip west/celbridge junction on N4.

[karlf]

It came from the celbridge side heading in the direction of intel, turned left and headed towards Maynooth at about 1.30am. They flashed their hazards dont know if it was at me or at the guy in the integra (i think). Dont know year or mdel as I didn't see much of it, they were going fairly hard. I'd guess at a Gpx judgeing by how fast they took off coming off the round about.
