Rubbish! While driving at 80 km/h reducing the speed by 5-10 km/h for a few seconds and then recovering to original speed would NEVER cause a traffic jam. This disturbance would be absorbed by not more than 3 or 4 cars and the 5th car would never feel it. That "butterfly effect" would happen at very slow speeds and bumper-to-bumber flows...Tiwaz wrote:You forget that slowing down in dense traffic multiplies with each car if there is no sufficient distance between vehicles.Karhunkoski wrote:Understand your logic, but I don't think the chaps mean a full-on braking session to allow someone to join from the ramp. I think what they mean is slightly easing off the throttle, perhaps reducing speed by 5-8 Km/h, in order that someone can join the flow easily. If you don't let them in, the cars behind get nervous about whether the joiner will try and muscle in anyway, so to avoid this they brake themselves, thus causing the jam that you describe above.Tiwaz wrote: Why slowing down on motorways is bad is that it causes traffic jams.
First car slows down 5-8km/h, next has to slow down 8-12km/h, one behind it has to slow down 12-15km/h and so forth until either safety distance has managed to eat the loss of speed, you run out of cars or total jam is created.
But, later on that one car you let join in front of you would be the last car to pass on the green lights and you stay... That's quite annoying, innit?
The fact doesn't bother me greatly, but your arrogant and introverted junttiness does. I have a choice whether to live in Finland or not, but I live here. You're just here.
