Amazing article. I've always been curious how hard it would be to simulate accurate tires in particular, and I'm also interested in how the sound of engines is generated.

A quick typo though: s/Imperically/empirically (I guess)

You are in luck, there is an amazing youtube series about someone who made an engine simulator so he could simulate engine sounds:

The simulation of tires is interesting too, because you can get totally playable vehicles without simulating them at all. Or you can simulate some aspects for gameplay reasons (tire wear, heat, rudimentary grip level change)

Or, you can go really, really deep, and simulate the real physics going on, and that's what games like Beam NG, iRacing, Assetto Corsa etc. are doing. Usually known as the "tire model" in case you want a term to search up. They're still approximations but ever improving accuracy.

		BeamNG is standing on the shoulders of Rigs of Rods, which uses soft body physics (points of mass connected by links that aim to keep the same distance between two points up to a certain amount of force applied, after which deformation occurs): https://en.wikipedia.org/wiki/Rigs_of_Rods
