Okay, well, from the top:
The show was never actually going that fast. It was supposed to be a race and no one actually seemed to care.
There should have been evil drivers. Bad guys. Something. It took them too long just to figure that out.
The Lost format doesn't work if you don't care about the characters. I don't care about the characters.
Who's in the lead? What are the positions of the drivers? Something to indicate that at all? Maybe?
From the very beginning it was a shitty concept for a show, Fox knew it, they handed it to Tim Minear (Angel, Firefly, Wonderfalls) int he hope that he could make it not crap.
And, just like when they did it with The Inside, he couldn't manage it. He's not a miracle worker, he's just Joss Whedon Lite.
