More Nitro in quick time
If you have used all of your Nitro in the Out Run races while in Free Ride Mode
you can quickly get your gauge back up full (even at level 3 Nitro).
All you need to do is reverse (make sure you look behind you at all times)
when you reach to speed reversein you will start to be given Nitro points.
Before you say this is bogus try it.
I got to over 1200 points while reverseing and it filled my level 3 Nitro instantly.
