The background of this photo and the track isn't blurry? I used to be a semi-pro photographer. I know a blurry photo when I see it. This photo is full of motion blur.
Here's an explanation of a photo finish using the same technology from a stage in last year's Tour de France.

The assumption people make when looking at a photo finish is that it is a normal photo, which has distorted images. After all, the bikes themselves, other than the spokes, look pretty normal — but the riders indeed look weird! But if it were a normal photo, there would be a background, and there is not, because the film is moving with the riders, whereas the background is stationary. This means there is no actual finish line to be seen in the photo, because the finish line is stationary — the entire photo is the finish line.

That photo is like the Lexus version of the technology, and whatever NASCAR is using is like a Pinto

The difference is cyclist move significantly slower than race cars. Pro level cyclist in a sprit hit about 40 mph.
Another problem with the system is it assumes all the object are traveling at the same speed (or relatively close to the same speed). It's also compressing a 3 dimensional space into 2 dimensions. To under stand the problem with this, you should read the book "Flatland" by Edwin Abbott Abbott.
