Free to play on Steam! It has a pretty addictive career mode where you need to win races to upgrade your car and buy weapons. The people you race against are a bunch of jerks though.
From Wikipedia :
In May 2009, programmer Jari Komppa contacted Remedy and volunteered to prepare an open-source release of Death Rally. Since releasing the game as open-source could not be agreed upon, Komppa instead started working on porting the game to Windows. Based on Komppa’s work, Remedy released Death Rally for Windows as proprietary freeware on 20 October 2009.
