Players start off with five vehicles; five more are unlockable.[2] The available vehicles range from a Volkswagen New Beetle and a Ford F-350 to a city bus and a Freightliner Century truck.[2] Unlocking vehicles requires completing goals[2][4] such as placing within the top three in any two races.[3] If the player has previously won a race mission, they can change the race's duration and the weather when replaying it. The Checkpoint mode allows players to set the frequency of traffic, police cars, and pedestrians. Vehicles can accrue damage from collisions, and can be disabled if excessive damage is accrued, resulting in premature failure of Blitz or Checkpoint races, or several seconds of time lost before the vehicle is immediately restored in Circuit races and Cruise.[5][6]
