There are 95 vehicle types drivable by the player. For each type, the game remembers whether the player has driven it. Each driven vehicle type counts a few tenths of a percent towards game completion. When the player (not his partner) starts the engine of a previously not driven vehicle type, the game will show the vehicle type and the number of vehicle types driven so far in the lower left corner of the screen. Driving the fifth vehicle type awards the Auto Enthusiast trophy. Since the police cars used change from partner to partner, this happens automatically during the plot. Driving the 40th vehicle type unlocks the Auto Collector award. Having driven all 95 vehicle types unlocks the Auto Fanatic achievement.
