I suspect if I brake tested a 40 ton lorry and got rear ended there may be some dispute over whos fault it was as well.. im not sure its always so clear cut
I know that its there as trying to sort out dispute, especially if there if there is no eye witness's around would be time consuming and more costly through the whole processes so a base rule resolves a load of those issues but it still sucks. I bet a lot of cases these days of people like us were giving the gap and at the speed limit but the people at the front doing it just at those daft movements.
Motoway, changing lanes your supposed to shoulder check to make sure your not bashing over a biker in your blind spot etc. The person randomly brakes hard because they dropped the hambuger they are eating (this sounds daft but I know similar true stories) and dumb ass brakes - You look and you got no time to brake properly.
