I dunno about the A5 in the states, but my A5 delivered from Australia isnt very safe at all. We actually did that test. I was about 10mtrs away from the car, my mate jumped in, started it and drove away. I was under the assumption that the car would pull itself up a short distance from where i was standing, though to my astonishment the car kept going and going until it disappeared around the corner!!! I dunno if there is a difference between here and the States but i was very concerned when the car didnt pull up at all!!!they can drive off but the car really wont go far with out the key which is mostly in my pocket, did a small test and the car only goes about 15mtrs and slows down and stops.
