If someone has bothered to build a multiplane highway in the US, it tends to only rarely be so underutilized as to resemble fairly open road. Even if it's not “stop and go”, much of the time it is continuous traffic at some speed in all lanes, not sparse traffic in the right lane (or even the lane just to the right of the leftmost) and no significant traffic in the lane to the left allowing one to use the right for all regular travel and only move left to pass and then return to the right.
And the induced traffic effect means that adding additional capacity doesn't actually change this meaningfully.
