Arrested in Bettendorf

I was going back to high school as an adult. I was driving to school before the sun came up (or perhaps at night) when a passerby near a car dealership that does not exist in real life entered the car and had a seat behind the passenger seat. I agreed to give him a lift to the high school. Moments latter a police car turned on it's lights and cop existed, tapping on the back window. Apparently, something was very wrong. Stolen car? Wanted fugitive? I can't remember. Next thing I know I'm in jail trying to get my cell phone to work so I can contact at least one family member. Got through to my mom and explained what seemed like a huge misunderstanding. I tried to explain how I was a high school student just on my way to school and was obviously innocent. One jailer or officer responded "then why were you taking the back roads"?
