Just how many lanes would be required for all drivers in the left lane to automatic move over one lane to let merging traffic in when there is no other traffic. Just wondering because 2 lanes isn't enough for some drivers.
I used to be a bit critical of the merging traffic here in WA. Now I think they don't have enough distance in their merging lanes to get up to speed. For me its not a problem as I drive like an idiot, but generally most people don't match their speed when merging and I think its because the onramps are a bit short. In other words, a lot of people won't hammer their cars trying to get from 60kph up to 100kph in the distance given, with only a small window where you can actually merge.
I was a bit surprised that a lot of people will change to the right lane to let people in, but it seems to have dumbed people down a bit as they expect it and don't try and match their speed. A lot haven't learned that braking is much easier to match the speed than trying to floor it.
I think 3 lanes are ideal. The right one for people to sit less than a car length behind each other at 110, the middle lane for most other people, and the left lane for me to cruise past.
