There are two solutions: Perfect Start and Super Boost.
For Perfect Start, the tip is to press the pedal as soon as you hear the fourth beep and see the "Go" text (on slower iPads, the players may need to press the pedal *before* seeing the word "Go" on screen).
To get Super Boost, the tip is to play a boost token (the one with an arrow icon on it) when you are on a blue Power Strip. You should toss the Boost Token right before you are about to drive onto the blue Power Strip.
In general, progress in Level 2 depends on the perfect start. If both of the players don't have a perfect start, you will get an error message.
