I took this picture in La Jolla this weekend -- it is of a house with a very narrow driveway that has a turntable to help the car get in and out of the garage facing the right way.
I thought it was amazing, but my wife immediately began saying things like "well, I think you could easily get the car in and out without it by... blah blah." I told her you don't have a turntable because it is necessary, you have it because it is awesome. Didn't she watch the Batman series growing up? It's a freaking turntable for your car! What further justification is needed?
