The "Need for Speed" series of games and the "Burnout" series are examples of driving games that have online multiplayer capability. Both are multiplatform games that provide differing experiences. "Burnout" differs from "Need for Speed" in that destructible cars are a main focus of the engine and gameplay in "Burnout."
Other games that have online multiplayer capability include "GRID 2," "Shift 2" and the "F1" series. These games have differing mechanics, with "Shift 2" being considered the best one on the market as of 2012, according to VideoGamer.com, ranking just below "Need for Speed: Most Wanted."
For driving games that are online, but not multiplayer, a number of websites, such as AddictingGames.com, contain free titles. These games are made in Flash and similar browser formats, making them available across a wide variety of websites and browsers.
