So on my way home last night and at a light where 2 lanes merge to 1 and when the light turns green we both go for it. And he was able to jump ahead of me but we pretty much stayed the same.. I did forget to turn nanny mode off however. The bike was one of those Harley type cruisers with the big windshield on the front. I didn't think those things could move that quick. I mean I'm not the best driver out there but I know how to bang gears pretty well. Could the nanny mode really limit you that much??
