Like many others I can't choose the Thunder Mesa nor Volcano Island flipped tracks, as well as the RipTide vehicle. Here's a little tip for those with patience who want to play those tracks and use the RipTide vehicle; At the location selection screen turn the wheel all the way to the left (Check Me) and leave it there, let the timer run out. This will choose a random track. Same thing at the vehicle selection screen. Sooner (or later ) it will select those tracks / RipTide. Not an ideal solution, but it's something...
