Pulled out of a parking lot behind an rx8. Unknown yr or mods other than loud as hell exhaust. Traffic was thick and speed limit was 35. He was slowing to 20 and slamming the gas over and over. We got onto the interstate and as soon as we got onto the onramp he got on the gas. I rode his bumper hard until I got onto the intertsate and easily went around him. I toyed with him to 130 and the look on his face was priceless as I wnt by. We got off at the next exit and I slowed down to try and give him another chance from a dig. No dice. He wouldn't even look at me.
