I never had any cars try to race me. I tend to ride pretty hard though.
Once I was splitting lanes on the highway in traffic the was rolling real slow. But this Dodge Ram, got halfway into the next lane as I was approaching to block me. I sat for a while then once they started rolling and traffic cleared a bit, I tried getting in the next lane and passing him and he tried to hit me. I was recovering from an injury to my shoulder and I hit these tar snakes while accelerating and got horrible death wobble on my ZX7R. I saved it and just took the next exit. Damn, that was some bullshit though.
Usually people get out of the way when I'm behind them, switch lanes. Something I've seen which is crazy, I'll be cruising in the fast lane just cruising though. And the car in front of me will get halfway out of the lane to the left to let me through. Like I won't even be trying to speed, but they go out of their way to do that and I feel obligated to go ahead and shoot through.
