It's very hard to recommend this movie beyond a general nostalgia for the '70s. It's a limp lazy effort that offers very little in the story, characters, humor, or even action.
The race itself feels small, despite what we're meant to believe. There's very little interaction between the few participants we see in the movie, the focus more so being the personnel duel between just a couple of them. If you're thinking the crashes make up for things, think again. The stunt work is nothing special, mostly just fireball explosions and a final ridiculous pileup.
A pleasant surprise was the screen time afforded to Dick Miller, a familiar face who pops up a lot during the '80s and '90s as a character actor. He actually has something to work with here and takes his chance well.
Carradine seems to spend most of the movie falling off the road, he does what you expect of him, but it's very by the numbers. Ultimately this feels like a long boring car ride despite its short running time.
