Need for Speed Payback

This is a story related achievement.

This is it. The big one you've been working towards through the whole game. At the end of Chapter 5, Outlaw's Rush unlocks. You're going to need two cars upgraded for this event as it's a three part race; a Race car, and an Offroad car. Both cars will be used and you're going against "The best racers in the country", so make sure they're upgraded well past 330-340.

Part 1:
This is a race using your chosen Race car. You'll be racing against several other opponents, and midway through the race three enforcer cars will appear to try and take you down. These cars, of course, are driven by the annoying people you've been racing against through Chapter 5. Nothing about this race is difficult if you've gotten this far in the game, and you only need to finish in the top 4 to advance.

Part 2:
This is a race using your chosen Offroad car. Once again you'll be racing against several other opponents, only this time the cops will be called and choose to target you and only you. Luckily, their killswitches won't work, so you really just need to drive faster than them and your opponents. This race actually has two parts within it. When you get to the airfield there will be a cutscene and the cops will disappear, and the second part of the race you'll just have to win against the computers.

Part 3:
Time to put Lina Navarro in her place. This is a race between you and her, winner takes all...all the city apparently. This game really does make it seem like world peace can be achieved through streetracing and nothing else. At least there's no cops, no enforcers, nothing to try and keep you from kicking her... Well, you get the idea.
