I Hate Traffic is about crashing and goal achievement. One level may be about crashing a 20 cars, another might be about shoving a car into a square target area, and another might be about throwing yourself in front of a semi to save a bus from a cluster of bombs. Its all up to you.
Change the Red and Green Lights to let cars pass bye. Lots of levels and it gets tough.
A pretty cool commercial about traffic lights fighting. Red vs. Green
