I've only been stopped twice on a bike and got a ticket both times but the officer wasn't a jerk either time.
I've had several tickets in cages and don't really remember any of the leo's being overly nasty or anything BUT then again I treat them with respect and know that they are just doing their job. I've gotten out of several tickets but have gotten several as well but deserved them most of the time.
I haven't noticed being treated differently either way.
*edit*...Oops... I did get pulled a third time on the bike for improper display of my tag while at Myrtle Beach, SC during bikeweek BUT they were definitely being rougher on people on bikes.
They've even banned bikeweek in Myrtle Beach now so this wasn't the norm EXCEPT for MB.
