It could be an undercover!

 

I know what you mean man. I was driving on the highway the other day and this firebird came flying up to my side and started revving the shit out of his motor. I just shook my head and kept driving normal. We were on a curve and there was traffic all around us..... This didn't deter him in the slightest though he kept revving and finally took off as if he were racing me. I just laughed and continued to shake my head as I watched this idiot diving in and out of traffic by himself, probably thinking he just smoked me or something. Funniest part is my car is completely stock, so I guess he assumed I must street race because I own the car.....

 

I've had my fair share of revving fools.
I remember being revved at one night by a stock red nissan sentra in bartram park (man it was tempting on that road) and a beige mitsubishi galant.

I can't help but laugh at people that rev at me, 99% of them are kids.
I usually give them a puzzled, "I give up" look as they take off and weave through traffic.
