I got cut up in traffic today and almost run off the road. Can I contact him with his License Plate Number?

You can go to the police and file a report with them. Alternatively - anyone can anonymously let some steam off on http://www.emailacar.com/ - you can deposit your message for him here by using his license plate number and he will no doubt google it one day and find this message, or he might use this site already. If nothing else it will help get the road rage out of your system without having to shout at anyone. I find it a relaxing exercise.

Your first answer is right, you can go to a police station and make a complaint, although the driver won't be charged, they will receive a warning through the post from the police!

of direction you need to record it! He of course demostrated highway rage and could be prosecuted by ability of the regulation. If all people on your loved ones is worrying approximately retaliation then purchase a gun. Or ask for police secure practices.

nope nothing really you can do and nothing the cops will do so only thing you can do is drive and watch out.. i drive for a living it happens every day if its not them cutting me off its me cutting them off just drive and move with the flow be happy he didnt hit you im sure it will happen a few thousand more times
