Here's an excerpt from an article that Hardigree wrote in 2010:

No video game has a better track than Highway 33 because, like Adam and Eve in the Garden or humans in the perfect first world of The Matrix, no one would believe it. Once you clear the campgrounds and fire station, there's no looking back. It's a driver's paradise. It's a road lacking in everything you hate if you like enjoying fast cars. Highway 33 has no traffic, no driveways, no law enforcement, and often no guardrails. (OK, I sort of wish there were guardrails.) What it does have is curves. Lots of them. On a map, the road looks like Muhammad Ali's signature.

Honestly, I see this hard to believe; I'll have to go drive it, speed through it, and drift it without having handcuffs slapped on me to believe it.
