Love said, i think, you must be careful about all races and racers.
Some racers found a race with impossible record, it was me , track A_Class ( i was falco before , it's past)
i got 1sec before snoopy , i explain them i got a car mod (nsx 99) and they understand it.
However, watch all records from all racers. It's can be a bug from a last race deleted before, happen sometimes, or worse , hack.
