coreflow has little differences from MD.
MD :
1. MD uses car's own power
2. when player gets in the car, car is "set" in somewhere in the air by SA engine in most of cases.
coreflow :
1. coreflow uses another car's power.
2. when cabbie/taxi jumps on the car, the car "blows" cabbie/taxi and get height, distance and rotation.
i got over one million fts with coreflow but i cant save reps. because my cabbie dont land even i waited for 40 mins. and my cabbie was on the sea.
so i concluded it cant be WR
