In this video guide I will show you how to bust a racer in the GUMPERT Apollo S Interceptor at night, online or offline. The location is called:
East Gorge Canyon, and the event is called:
Lockdown.
Keep in mind this is the cop side of the story, and you will
need to be at level 20 to unlock the car. This is the easiest way I found to get this achievement. Doing a hot pursuit in story mode gives you more racers to takedown pretty quickly. Once you take down a racer by any means the achievement will pop right away.
