Horsepower and weight are normally irrelevant factors in Prostreet. It is possible for players to get a 475bhp Nissan 240SX to outaccelerate a 1,001bhp Bugatti Veyron 16.4 through the use of exploit-related tuning.
Players can use the vehicle reset feature to gain access to outside-of-map routes.
There are certain places on the Nevada Highway where players can find gaps within the terrain. These gaps can cause players' cars to fall through the bottom of the map if they are driven over.
The Blueprint Share feature can be used to override the protection on Collector's Edition Cars. A player who owned the Collector's Edition upgrade could upload a blueprint for a Bugatti Veyron 16.4. This blueprint could be downloaded by someone who did not buy the Collector's Edition upgrade and allow them to purchase the Bugatti Veyron 16.4 although it would cost 1,700,000 credits.
Sometimes, after the player finishes a race, the "Continue" button doesn't work, this bug mostly occurs after winning a race, restarting the race won't do anything (PC).
Solutions to this include disabling the Autosave feature and anti-cheat Punkbuster software.
