Air shocks..why?

I have ran air shocks on every old mopar I have owned . It was the cool factor for me . I do have to say they do ride a little rough when aired all the way up . I had a cop pull me over in a 70 cornet back when I was 18 says my rear tires were crossing the center line in the road . And that the rear of my car was setting to high and it was to loud . And the purple dots in tail light were against the law . So then he proceeded to ask me if I had been drinking . I told him I don't drink and he started to give me good reasons for what happened he says maybe it was because my rear tires were so wide M 50 s And I was like yep that's probly why lol. So he followed me into town and I pulled in gas station and put the air to the shocks as I lifted the back of the car . I left out of the station with a rake out of this world stink bugging along as I passed the same cop he just shook his head at me but I felt better when he said the car was to loud I let him look under the car to see a brand new set of duel exaust just installed days befor I still run them on my 71 charger .
