How to unlock the Hard Crash achievement in Watch Dogs - Definitive Guide
To perform a vehicle takedown, you'll need to hack the world around you to bring it to a complete stop. You'll normally get a visual like the camera panning around and showing you the crash in slow motion when you've done it right.
The vehicles this normally work on are the police or Fixers while you're being chased. As you drive around trying to lose them, hack a junctions traffic lights, close a door or bring up some barriers.
A sure way to get an instant takedown is to look out for the 'Neutralize' within a blue square popping up on your screen. Holding as soon as you seen this will cause the car in front or behind you to instantly crash and this will count as a takedown.
This is nearly unmissable. All you need to do is to damage and take out 10 enemy vehicles while in your own vehicle. Since there are many missions (main and side missions) that require you to take out remaining enemies or escape, just use this time to ram the other vehicles until they are destroyed. You will get this naturally while playing through the game.
There is a skill in the Driving branch called "Offensive Driver" that will give you more collision damage to enemy vehicles, but you'll probably have this trophy well before you unlock that.
