Historical plates any cop problems ?

I was driving home from church one morning and stopped into a grocery store with my dart. I had raced it the night before and didn't get around to putting the caps back on yet. I am literally coasting through the parking lot and a cop pulls me over and gives me a hard time about my plates and exhaust.

Other times it's been late at night and the cop wants to see if he can catch me drinking and driving.

At the end of the day it's just one more thing to get pulled over for. I think the whole tag crap is just a way to make money off us. Normally I'll just throw my plate on from 73 and cops see it and assume it's out of state plates and leave me alone.
