i am using the GT v1, and i am experiencing a problem, where if i ever tap the brakes, the car hesitates for moment before it gets moving again. i mean i am just tapping the brakes and then getting right back on the throttle and i lose time waiting for it to get moving again. any idea what could be wrong?
