Free Driving Simulator

[Bildon]

For those looking for a driving SIM less commercial, less flashy, but more engineering based and FREE check this out: http://www.racer.nl

Racer is a free cross-platform car simulation project (for non-commercial use), using professional car physics papers (SAE) to achieve a realistic feeling. Cars, tracks and such can be created relatively easy (compared to other, more closed, driving simulations). The 3D and other file formats are documented. Editors and support programs are also available to get a very customizable and expandable simulator.

Note: My first impression of this is that it is really bad. The default 3rd person view is terrible. The physics seem poor. It may need more fiddling but don't get your hopes up.
GTR and rFactor make this look really bad though.
