David Tracy is a great guy. He works with/for Jason Torchinsky who is a really great guy, and a good and long time friend of mine. (Jason is flat out the most knowledgeable car person I know; huge fan of underdogs and misfits, his daily is a Pao (kei car).
David knows his shit. He's more tech than Jason, together, with other car crazy folk like Mercedes (that's really her name) make Autopian great. They were the talent behind Jalopnik, which was ruined by Thiel backing hulk Hogan to take down BuzzFeed.
David was a cooling systems engineer at Chrysler, amongst other things, and got me straight when I was designing my electronic cooling system. He always has the worst possible cars in terrible condition; you'll have to read his stuff to know why! Lol.
