Addendum: A friend emailed me this tidbit.
You're missing the best part. Pretty much got to figure that the engine is between the two (rather narrow) back seats. So the kids have to reach over the engine doghouse to bother each other. And they probably can't hear each other either. That helps eliminate fighting in the back seat. So you get a great ride, and the kids are trapped in solitary confinement. Gotta love that.
