Dear JimTullis,
Wow. Thank you for the excellent list. I was not aware of the anthology, "Death on Wheels." The book is now in my crosshairs for capture.
The Auto Assault Soundtrack, published on a CD for the former MMORPG, has very good music for tabletop car combat.
The music from Interstate '76, Interstate '76 Nitro Pack, Interstate '76 Official Game Soundtrack, and the Interstate '76 demo album Bullmark is great for driving both on a tabletop and on actual highways.
I have a few titles of books and movies that may interest you on the Web page below.
