You might want to consider an adaptation of the method MrsS has adopted of influencing the attitude of police toward grandmothers who are pushing that envelope of 'niceness' ...

She has a picture of our policeman son (in uniform, of course) that is right next to her driving license ... and naturally, that picture is very liberally displayed as she 'struggles' to get her driving license out to hand the officer that has stopped her ... she has even quite shamelessly drawn attention to the picture if the cop in question doesn't comment on his own ... it is nothing short of amazing how well this 'auxiliarry insurance policy' has worked for her ...

And, while you may not have a policeman son whose picture you carry, the cop doesn't necessarily know that ...
