... and get thee over to the IAM website, where there is a poll in the use of headlight flashes. I think this is in response to the chap who was prosecuted recently for warning oncoming drivers of a speed trap.
The IAM view is that we shouldn't flash our lights at all, as it is not mentioned in the Highway Code and any 'message' could be misinterpreted. This is a reasonable point, although it ignores the fact that in the real world there is already lots of flashing going on, and we have developed a fairly sophisticated code - long/short, single/repeated and so on. I can't describe the code here, but I would say that I have rarely, if ever, misunderstood when someone has flashed me. 9 times out of 10 it is a polite 'after you, Cecil' - the other one time, there is usually no misunderstanding of the guy's hostile intent.
The IAM are interested in getting as many views as possible, so get over there and spend two minutes helping them out. There are some text boxes so you can make your meaning perfectly clear. To be fair, the options cover all shades of opinion. You don't have to be a member to take part.
