[quote name='cdietschrun']So if I see the red street signs I try to start racing somewhere? Or hold L1 then R1? And try to make a crash? Sorry...I didn't catch any of this in the first few hours of the game.[/QUOTE]
If you pick Showtime, just hit L1 and R1 anytime to start crashing. If you picked Time (or whatever it's called) you just have to start at one end of the street, and head for the other end of the street as fast as you can. I believe the street sign is red if you haven't broken either the Time or Showtime record on a street, it will be silver if you broke one of the records, and gold if you beat both of them.
