I'm cruising on the highway, and I can see him creeping up getting closer and closer. I drop to 3rd and lean into the throttle to keep him from passing me. I surge ahead a little and then let him catch up, and I do this a couple of times. We close up on some traffic ahead, and I slow down to give myself the chance to jam the brakes if anyone pulls out ahead of me. I'm in the left lane, the middle lane has some cars, and he jumps into the presently open right lane to go flying past everyone. So I let him get ahead, and pace him for a few seconds. He's about 5 cars ahead, and I go to WOT, and just start reeling him in. I pull past him and put about a length and let off. Seems like he just wants to stay in it and pulls ahead of me. I slow down for my exit. So then I see him tap his brakes. I wonder if he thinks he won - perhaps the way he might define it, he did? But it sure looks to me like a mostly stock WE4 pulls harder on the top end than an S200 though. I would think he would do all he could to keep me from pulling past him, but that's just me... Maybe he had some kind monster engine, that he let me catch up to him, and then showed me? I doubt it. He didn't pull on me at all until *I* lifted
