I get a laugh out of rednecks dusting Priuses, but they are just increasing the cost of diesel ownership.  It took us a long time to get rid of the ripoff safety inspections that occurred until the mid seventies and we might yet get rid of the federally mandated tailpipe gestapo that does nothing for modern self regulated ultra clean vehicles that demand service with the check engine light  if the gas cap leaks air.  But not if we have a bunch of showoff dope smoking children with ham handedly modified $60000 vehicles daddy bought for them. Let's learn to lay low, chip the engines maybe, but don't ruin it for everyone.
