Is it just me, or does everyone have this problem? The rear floor liner fits perfectly. The passenger side fits good, but the drivers side is horrible. Not much of the drivers side floor liner matches the model S contours there are very large gaps(1 inch), where mud, snow etc can get under the floor liner. I just cannot imagine that it was designed this way. I tried calling weathertech, but their customer service Sucks. They don't really care. The thing is, I don't know wheather this is a one off issue, or if the designers were asleep when they measured the drivers floor of the Model S.
