Don’t Blink
Shut down Most Wanted car number 1: Koenigsegg Agera R (Single Player)
Car used: Lamborghini Aventador (without any tuning, only Nitro customization equipped).
You will unlock the last Most Wanted race after getting 1 million speed points. Speed points are a reward for winning races, exploring the world, beating autolog recommendations and escaping the cops. Use a really fast car for the last race! After finishing first you will have to take down the Koenigsegg Agera R by ramming it. This will end the actual “story”, but you can still free roam and get missing collectibles or repeat your favorite races!

Kitchen Sink
Used a Billboard and a Jack Spot to successfully evade a pursuit (Single Player)
First of all you need to attract the attention of the cops. Break the speed limit, cause some property damage or drive into a police car to make them chase you. You will then have to destroy a Billboard, change your car at a Jack Spot (Triangle on PS3 / Y on X360) and escape the police. The Billboards respawn, so don’t worry if you have destroyed them already.

Fast Forward
Triggered a speed camera at over 200mph (321.97km/h)
You will need a vehicle with good top speed stats to accomplish this (e.g. Bugatti Veyron or upgraded Lamborghini Gallardo). There are a total of 66 different speed cameras. You can trigger them how often you want. Search one on the highway and use nitro to reach the 200mph. Beat drivers on the Most Wanted list for their fast cars and win races to acquire upgrades. Especially the long gear customization can be very helpful when trying this!

Escape Velocity
Jumped over 200 yards (182.88 meters) through a Billboard
You will need a really fast light-weight car to do this. The Ariel Atom 500 V8 is a good choice. Try to get all upgrades for it and equip the Powershot Nitrous customization. There are a total of 156 Billboards. However, only very few of them make a 200 yard jump possible. Look for two circular glas structures on Gunderson Avenue North (pretty much in the middle of the world map). Both of them have a Billboard and can be used as a huge ramp. The Billboards respawn, so don’t worry if you have destroyed them already.
It’s very important that you do not crash your vehicle when landing. Neither will the game recognize that you destroyed the Billboard, nor will it give you credit for the jump if you crash.

Sidewinder
Did a 250 yard (228 .6 meter) drift
Drifts can be done by using the brake while driving at medium speed and steering left or right. Parking garages are a great place to do this. One can be found on Bloomguard Street (around the center of the world map). Get a car with good handling and drift your way up the garage.
