Not as simple a problem as it seems, to handle automatically. So if the "Red Sea" of cars in front of you opens up, how should the car know to NOT accelerate to 70mph if the TACC is set to 70? Well, if the cars on either side are also basically stopped, the car could infer that the just opened up lane in front is a temporary open lane in an otherwise stop and go traffic pattern. Case closed right? Just look at the speed of the traffic in the surrounding lanes and don't accelerate to 70, but something less based on them.
But then there is the case where you are in an express lane and going 70mph and the next lane over is stop and go. The car would then have to be smart enough to know that in that case it should ignore adjacent lanes when deciding whether you should be going 70 or accelerating to 70.
