got a speeding ticket , need help!

[Benefit]

ok so i had just got done fighting my girlfriends brother...im going back home , and get pulled over

officer looks at my hand , my face and says who did you get in a fight with i said no one...

so he calls me outside talks to me , i told him the story he filed an injury report, i get back in my car

he comes to get my friend out of the car...and i ask him why am i being pulled over he says ill get to that in a little bit

so he tells me im doing 80 in a 45, when i damn sure KNOW i wasnt , there was other cars around me , i was moving with them...there was even 2 cars in front of me that were blocking both lanes...the officer even mentioned this, hes like "oh if they would have moved , then you would have sped through"

then on TOP of that he asks me "have you ever gone fishing?" i say yes "you cant catch all the fish can you?"

wtf is that?

i know i was not speeding , for all i know he is eyeballing that i was going 80...i was moving WITH traffic , 2 cars in front of me blocking both lanes...and it was a construction zone so im double ****ed..

i need some advice on what to do...

oh he told me to get a slower car too...wtf
