I got my first Pfizer shot at the Charlotte Motor Speedway a week ago. It was quite organized. You drive around the track and through the pits and into the infield to various stations along the way. Then when you get to garage bays, you get your shot in one of them. You never leave the car. They did have cones preventing you from driving on the highly banked part of the track, which you probably need to be going at least 100mph to stay on. I didn't see anybody in mittens, though.
