Five of them are the five kinds of traffic the game is built from, and the sixth is the one the game built a whole bonus mode about.
The Kiasu Tailgater
You are the reason the game has a whole mode about following distance. Tailgate Champion fills a Kiasu Meter every time you ride a bumper, and then the car in front brake-checks you. Try Tailgate Champion.
On a real road Leave three seconds of gap. Count it off a road marking: pass it three seconds after the car in front does.
The Rammer
In the game, a rammer waits until you come close, then comes for you: from ahead it brake-checks, from behind it floors it. Then it backs off and tries again. Meet them on level 6.
On a real road Road rage is never worth it. Let them go, and let the camera deal with them.
The Speeder
In the game, a speeder arrives from behind faster than you can go, and dives for whichever lane is clearest every second. They arrive on level 3.
On a real road In a car in Singapore, up to 20 km/h over the limit costs S$200 and 6 demerit points, and it only climbs from there.
The Drifter
In the game, a drifter slides across the lanes every couple of seconds with no signal, often straight at you, and follows you onto the shoulder. They start on level 1.
On a real road Signal first, check the blind spot, then move. In that order.
The Braker
In the game, a braker cruises along like everybody else, then for no reason drops to a fifth of its speed, brake lights blazing. They are on the CTE.
On a real road Brake early and smoothly. The car behind you is not reading your mind.
The Cruiser
In the game, a cruiser holds a steady speed and changes lane now and then. It is the one car on the road you can read, and it will save your run. Read the game like a cruiser.
On a real road Keep doing exactly this. The rest of the road is in the other five results.
