You should always try to get their numbers and report them to the local constabulary. Make sure you emphasise the fact the were driving dangerously and in an intimidating and threatening way, and that they forced you from the road. Make sure you get an incident number. If you do this plod will have to (begrudgingly) track the bastard down and explain the highway code to them. You should always ring back a week later to make sure they have and get the 'We spoke to them, blah blah, evidence blah, blah, no charge blah blah' response. Eventually the drivers will learn to curse you under their breath, but hopefully not actually try to kill you.
