Black Ford Kuga. Overtook line of traffic on single carriageway coming out of Porthmadog. Cut in front of me to avoid head-on collision. After I beeped, male passenger opened his window and sat on the sill whilst gesturing for me to pull over (presumably because he/they wanted a fight?). Female driver swerving around, braking hard in order to initiate a collision and gesticulating. Male passenger then brandished a pair of shoes (yes shoes) and made throwing actions. Dangerous road user to say the least.They had at least 1 child in the car, as did I.
Appauling, foul mouthed and incredibly stupid. Needs to read the highway code.
