Well done posting this. This is why I like the dash cam. Keep calm and post in this site. No need to be agressive. I gave thumbs down to this driver. Even if police do not investigate this, insurance companies will do, and it will be an extra cost of their annual insurance fee.
This person has smashed the back of my Dad's car good job we were not in it or no children running in front because she actually moved our car I hope she pays for smashing our car.
Appaling lack of common sense or decency, also may want to look up the highway code on the right of way.
