Maybe that's the real reason why

I think circumstances dictate things. Pulled over on the shoulder is dangerous; let the nice person in uniform come to you. Years ago, I pulled over in a parking lot for what I presumed was a tail light out or something (expired tag) and I just jumped right out.

Maybe that's the real reason why I got the full-car drug search!
