Each event gets harder and requires the player to use faster cars to reach first place.
Each location is connected in "Sprints", so hypothetically one could drive from River City (Paris) and end up in Harbour Town (the Costa del Sol) in a matter of seconds.
The Boost meter can be powered up by driving down the wrong side of the road, drifting around corners at high speeds, narrowly avoiding traffic, completing a lap without crashing, or swerving to avoid a collision.
The crash is then shown from several different angles, and a replacement car then appears without damage, but with a loss of some accumulated boost.
This can then be used to produce a Burnout (an increased acceleration of the vehicle) until the boost meter is empty.
