In theory at least, the Model S reservation is for me and the Model X reservation is for my wife. She's going to have to get around her initial shock at seeing the falcon wing doors. If they really only need 7'2" to open then it'll fit in our garage no problem but she's going to have to get around her preference for understated styling (she currently drives an LR3, aka box-on-wheels, and had a Pilot before that, aka milk toast). I have a suspicion that, once the Model S arrives, she's going to do a lot of the "I have a lot of errands to run around town today and it would make a lot of sense for me to drive the S so I don't burn all that gas in my Land Rover." The thing is... I'm going to let her because she'll have a really good point. There's no reason for the Model S to sit at my office all day while she runs around town at 14 mpg in her car.
