Defeating Beat
When you have to race Beat in the street race, you will get to the point where you have to copy his exact moves, grind on the rail, break through the glass, jump on both rooftops, then jump off and finish the rest of the race. You will get at least around five corners from him but you will hear his roller skates. However, if you look on your map his dot will be far from where you are. Keep going, but do not take your time or he will "boost dash" and knock you down.
