reckless driving-hit stuff at high speeds

A8: Quick statement, though ["Buy a lamborghini gallardo, that's what I did" (quote)] A good driver needs no faster car, or nitrous for that matter. I upgraded the tires and suspension and got a small turbocharger (not the best option) at 5th gear got 200 MPH on mazda RX-7 The trick is to get up to good speed and practise easing off the accellerator and that will close the valve alittle (the yellow thing in the RPM/MPH dial) and it will help you again. Turning slowly and apex turning, as well as a better understanding of how not to drift are essential. Anyway, I just wanted to say that, because I just mastered it. Kick-ass!

A9: I have gotten all 8 be for
for NFSMW I have Approach in Caution
in my police Record and they do approach in caution
