I'm sure they could then fine you for obstructing traffic for driving too slowly. Or for indicating too early, or too late. Or for not keeping enough distance from the vehicle in front of you. Or because you used your horn. Or for not using your horn perhaps. If they just kept following you, sooner or later you'd make a mistake. Ticket quotas have been discontinued or made illegal in many places.
