In this mode, you are free to drive around a highway with a variety of other cars. Street races can be initiated by pulling up beside a car and pressing the shift light on the center of your dash. A crown icon will shown up above the competing car and a 25 second timer will start.
Since there are many other vehicles on the road, you will have to change lanes to avoid them while trying to beat your opponent. A red exclamation mark will be shown on the right-hand side of the screen when there is a car ahead in that lane. This can be used to avoid obstacles before they come on screen. Although useful, these warning indicators are ineffective at higher speeds because the warning will not give you enough time to change lanes. The only solution for this is to slow down.
If you are ahead when the timer completes, you will be rewarded. If you are not, nothing happens. The game does not end when a race is finished like in other modes. You can continue to race other cars as long as you wish.
