The reason the limousine slow down is hard to discern in the Zapruder film is because a) there are no figures in the background to serve as a referent b) the limousine is moving left to right and the panning is moving along with it and combined it creates the illusion of steady pace.
One of the clues to seeing the limousine slowing down is to try and follow the pace of the panning camera. Zapruder is doing his best to hold the limousine in the center of the frame. The panning motion doesn't come to a rest, but it does slow in concert with the vehicle.
