My favorite (MYLR) challenge has a slightly different "spin" in that I cruised passed my opponent going about 30 mph. I was stopped at a light and some guy pulls up next to me, looks over, and starts revving his engine... you know, with "the look". I sat up straighter, hands up on the wheels, looking forwarding intently, and the light turns. He peels out to get ahead of me, and I never even moved. I put my foot on the accelerator gently and cracked a slight smile as I drove past him pulled over on the side of the road with the flashing blue lights behind him of the cop I had seen parked on the side of the road ahead. Remember to evaluate your environment for any possible leverage to win with the least effort possible.
