Hack the blockers at the right time and you can flip a car so that it is resting upside down. When you do that, a driver will exit and leave the scene. Flip the car again, though, and it should drive away after a few seconds (without a visible driver).
Easy Shell Game Win
Begin playing the shell game and let the hustler finish moving the cups around. Without indicating which cup you believe hides the shell, pause the game and access the Options menu. Under calibration, set brightness to 100 and then unpause the action. Next, pause it once more. For a brief second, you should see the outline of the ball in one of the available cups. Choose that cup to win the round.
Skill Points Exploit
Buy plenty of ammo at any store that sells it, and earn yourself a wanted level. Hide out in your safe house, in the bathroom.

Digital Trip Barrier Trick (Alone)
There is a Digital Trip you can activate, called Alone. In it, you must free numerous districts. The robots within each district cannot pass beyond certain barriers or they will die. Use that fact to your advantage. Enter a district, wait for a group of robots to spawn, then lead them on a chase that ends outside the barrier. When they follow you, they'll die as they attempt to pass through the barrier. You don't receive any points or equipment as a reward, but there's a delay before more robots will appear and you can use that to engage in more meaningful activities within the districts, before the threat level increases again. That makes it much easier to approach the generators.
Forrest Gump Reference
When you run into people they say random lines of dialogue. There is a chance if you "run" into a person, someone will say "Run, Forrest, Run!" It's a famous line from the movie Forrest Gump.
Aisha Tyler Appearances
In the Campaign Mission Wrench in the Works you'll find actress and Ubisoft press conference spokesperson, Aisha Tyler, talking to another NPC.
You can also see Aisha in what appears to be a hotel room or lounge talking on the phone. In the City Hall building in the Loop district, there is a City Hotspot. Nearby is an unmarked 'intrude' console which Aiden can hack. Doing so accesses a camera where you can watch Aisha on the phone telling someone not to worry about her being followed, and humourously discussing her fart
FarCry Blood Dragon Easter Egg
During the mission "Grandma's Bulldog" in Act II, you'll head through an area that includes an arcade. Players are gathered around an arcade cabinet. Look closely and you'll see that they are playing FarCry Blood Dragon, a reference to the downloadable content of the same name that was released for FarCry 3.
Assassin's Creed Easter Egg
In Aiden's Bunker hideout, accessed during Act II, you can discover a video log. A son plays through an execution scene and its aftermath in Assassin's Creed while a confused father watches and asks questions.
Rabbids Easter Egg
In the mission "Big Brother," while you're inside the house, walk into Jack's room (it's on the end of the hall to the left) and you can interact with a Rayman: Raving Rabbids toy. Turn it on and it will make the characteristic scream for which the rabbids are known.
