Talk on the phone or park your car. But don't do both

I drive a little car, so maybe I just don't understand. Parking my car takes about 5 seconds and no skill at all, so maybe my opinion comes from too narrow a focus. But, after watching someone struggle to park her gigantic SUV next to my little car, I decided that auto dealerships or the DMV ought to create a parking test for people who want to drive an SUV. If you can't park it, you can't drive it. If you can only get it into the spot kinda straight, then you can't drive it. I realized after I had created this lovely parking test in my head, that my little friend trying to park her unnecessarily large truck, was actually just talking on the phone and trying to park with one hand... Of COURSE you can't park a huge car straight with one hand! What was I thinking?
