If you easily beat that... you won't be able to beat this (never done this because I don't have the game, although I did do something similar in NFS World which was Mass Murder v1):
Mass Murder (v2)
Heat Level 8. Any legit game car allowed. You are allowed to use a maximum of ten pursuit breakers. (V1 was unlimited, but you had no nitrous)
Disable 200 cop cars. No Speedbreaker. (Version 1 was disabling 85 cop cars in a crappy Nissan GTR in NFS World) No hacking. Evade after wrecking 200 cop cars to win.
Also this challenge:
"What's the Problem, Officer?"
Cause a chase lasting for 20 minutes and evade it while staying under (depending of challenge difficulty):
Easy: 80 mph
Medium: 60 mph
Hard: 50 mph
Masochist: 40 mph (beware of going too slow and getting busted, stay above 30 mph I think?)
Insane Person: 31 mph (you will get busted if you drop under 30 mph in World, idk about carbon)
Heat Level 8 (again), pursuit breakers allowed, any game car allowed, no speedbreaker, and no nitrous. Only things you can do in the legit game (aside from heat level 8) are allowed.
Should you exceed this speed intentionally (an unforced error like ignorance of the speedometer, etc.), you instantly fail. If it is unintentional (as in a forced error like a cop rear-ending you), then you must slow down to the speed and continue going.
