Beat the start

Five red lights. When they go out, hit Space (or tap, on a phone) as fast as you can. Your reaction is your launch: the quicker you are, the harder your car slingshots to the line. You're in Georgia's No. 2, dead centre of an 11-car grid.

Finish on the podium to unlock a pixel-art iPhone wallpaper of Georgia's car, with a different design for P1, P2 and P3.
