Realistic driving experience

[NaN]

The AI, racing logic expect closed loop tracks. But you can run the game without any roads at all, drive directly on the track mesh.

Bullet is used for collision detection and rigid body dynamics. Powertrain, suspension and tires are handled by custom code.

There is no special code to handle Pacejka related issues in the simulation. The forward rolling is one of the symptoms. It might be possible to hack around.

At some point I rewrote the simulation (sim branch) to deal with the limitations of current code. Unfortunately it turned out to be computationally too expensive to simlate multiple cars.

I still hope to get back to it, slowly working towards separating simulation from the rest of the game, to be able to go multithreaded eventually.

Recently other things had higher priority though.
