Ok so I've just driven another 100 miles on the highway. I've come to the conclusioon that the issue was pretty much in my head. But I will say this: the highway steering feels much different than driving around town. I have never driven a car that has electric steering like this, and am not accustomed to it yet.
I tried hard to keep the car in its lane and I was pretty much able to for the most part. The electric steering just feels funny some time but its actually not that big of an issue once you get used to it.
As of now I'm thinking that its not even an issue. Hope I didn't worry anyone too bad, lol.
