USA race etc  - To race you have to tap the icon in the lower right corner. To get a good start, you want to stop the needle pointing directly upwards. During the race you will get the option to use boost. Tap it and then tap it again when the moving line meets the horizontal markers to get the best boost. After using the boost, you will get a 3 second countdown before you can use it again.
