I have reading on this forum about the track key and read that the red key is all that some of you use. Is it worth it for me to get the track key? I do not track or plan to, I use my Boss to get back and forth to work and I at times get stuck in bumper to bumper traffic here in D.C. I read that sometimes the car bucks forward with the track key and would hate to hit someone in front of me. Just looking for thoughts if the track key is worth the money since I do not track the car and deal with alot of traffic.
