My experiment

For the past four weeks I have been covertly [read: unintentionally] conducting an experiment. Hopefully today was the last day of the experiment for a while. In four weeks, Aiden and I have taken 3 trips to his pediatrician in Edina. Edina is a pretty affluent suburb of Minneapolis and therefore was the perfect site for this experiment. On each of the visits I have been observing the way cars are parked in the parking lot.

Hypothesis:
I left our first visit with my hypothesis, "The richer you are (or the more expensive car you drive), the worse you are at parking." Aiden left with a diagnosis of walking pneumonia.
Data:
Trip #2 confirmed my suspicions as Aiden and I attempted to walk between two cars that were parked completely crooked, one was a Range Rover and one was a Saab. That trip Aiden came home with a bill of good health and a few "owwies" from shots. Today was (again, I say hopefully) the culmination of my extensive scientific work on the subject of poor parking. I parked in front of a Cadillac that was over the line and crooked. Next to the Cadillac was a brand-new shiny Jeep, parked crooked. Now, don't get me wrong, when I say crooked I don't mean just a little bit, I mean "have you been drinking?"-crooked. Aiden departed this time with a diagnosis of an ear infection.
Conclusion:
Needless to say I think my hypothesis has been proven. Now the question remains, are they bad at parking because they truly lack the ability/eyesight to park straight or is it just that they don't think they have to park within the lines?
