AITAH for talking back to a police officer?

So I was on a roadtrip with my whole family and I was driving the speed limit and as I was going down the highway a police officer is trailing behind me I stop on the side the police officer stops because I was going 1% under the speed limit as I said before at the start of my story I genuinely thought I was going perfectly.

I was already mad because the kids in the back of the car were screaming "ARE WE THERE YET!!!" and it is SO bogus to pull someone over for going 1% under the speed limit so I told him "I was only going 1% under the speed limit and I said sir this is unfair that you pull me specifically over when there are people literally speeding right next to you, so you are going to get back in your car and I'm going to go have a good day sir goodbye." I closed my window and drove off as I was driving off I looked at him in my rearview mirror and he just stood there probably thinking about how he should be doing his job instead of bothering me then he looked at me and mouthed "I'm sorry." I nodded in my rear view mirror as he walked back to his car. So do you think I'm in the wrong or is he??? let me know
