"Dex, you are just plain wrong, in Qld anyway. It is the merging drivers sole responsibility to join the flow of traffic safely. They have to give way, just as you give way at a T-junction. The rules are the same - except that you must adjust your speed to that of the traffic that you are merging with. Nobody has to take any action to let someone in. The Qld rules are very clear on this point."
jantimot...I don't agree with that statement. To zip up a zip both runners have to be working perfectly and mesh harmously...if I may use that analogy.
Sometimes I can not adjust my speed to the speed of the freeway because not all cars in the acceleration lane 'realise' we are not on a Sunday drive on a scenic tour. Hence...cars already on the freeway side of the merge lane should not charge in at maximum speed...that is unproductive as it causes braking and in a worse case scenario...an accident.
Due to my work...over the last 3 weeks I have looped a section of our freeway in excess of 90 times and it's always the same old same old...attitudes combined with a lack of the road rules that cause congestion and accidents. Density plays a very small part. Traffic may not be able to do 100 but if the cars all drove according to the rules with a strong dusting of courtesy...a flow will be maintained. Throw in attitudes and the whole system meshes the cogs.
