Dangerous driving, driving without due care and attention and using a mobile while driving.
This idiot cut in front of me at the junction at the top of the road and then proceeded to stop at a green light and refuse to move and decided to go on their phone.
Foul mouthed girl began swearing as I overtook. Reported to South Wales police for the above offences with evidence.
Following another vehicle at 0.24s @54mph will get you in trouble. I'd like to see you do that to an unmarked car!
