I did my "double" at Charlotte as a gift for my 70th Bday. The experience was superb and truly a once in a lifetime experience. The disappointment came after getting back home and looking at the In Car Video which was purchased as an add on to the gift for more than $100. At check out the video is promised to capture the memory of your once in a lifetime experience. What we actually got was video footage shot from the dash of the car depicting the track as I went around. Nothing of me in the car any my reaction to the thrill of the experience. If I did not know I was driving then it could have been anyone in any car doing the driving. Not worth the added cost for such a SD card.
