Sure, it's got an unobstructed view...
But let's say you're at the park with your girlfriend and another couple. Everybody decides to go ride Deja Vu and gets in line. After the (probably lengthy) wait, you step up and look at the train. Then, you realize...
If you want to have both couples sit next to each other, they're going to be separated by that offset. If you decide that you and your girlfriend are going to sit in the front seats, then you find that your friends are not only separated by the two middle seats, but they can't see each other either!
Since the vast majority of people who go to parks go with at least one other person, I think that design is pretty atrocious.
