I had not much experience writing artificial intelligence, a tiny bit of pathfinding, decision trees, and a few other basic things that were class assignments or the such. Wouldn’t it be cool if the artificial driver had to work with the same knowledge and inputs as the player? You know, instead of directly moving the vehicle to the new location, the accelerator, brake and steering inputs would be used. The books also mentioned how important reference points are, so the driver should also use these!

Here is a short recording of the artificial driver, Jared, driving at Fern Bay Club in the XRG. A fantasy car similar to a low powered rear-wheel drive sports car.

The second version/iteration of driving logic was written last year, March 2015, but my PC at the time was getting outdated and overloaded as it tried running everything it needed, plus AIRS logic could use some optimizations. I lost motivation after writing “Driving Logic version 2” (DLv2 for short), since it didn’t behave as well as I had hoped.

The driver got faster than DLv1, and learned
