The author concludes that the crosswalk safety features are a waste of money because more pedestrian injuries occur at crosswalks with these features than at crosswalks without them.

The author compares the number of injuries at crosswalks with safety features and crosswalks without them. He assumes that these crosswalks are similar to one another in all relevant ways, but there could be some important differences between them. For example, maybe far more people cross at the crosswalks with safety features. Or maybe these crosswalks are more dangerous in the first place and the safety features make them much safer, even though more injuries still occur at them.

If the crosswalks got safety features because they were the most dangerous, there would likely be even more injuries without the features. Even though the safety features haven’t completely eliminated injuries, the author can’t conclude that they’re a waste of money.

The author never claims that the safety features “fail to reduce the number of injuries,” just that more injuries occur at crosswalks with the safety features.

The author doesn’t propose any alternative measures for reducing injuries. He never assumes that less expensive features will be as effective, he just suggests that the current features aren’t effective enough.

The author only addresses striping and flashing lights, but he never assumes that these are the only safety features at crosswalks.

The author only addresses pedestrian injuries. How these injuries compare to drivers’ injuries is irrelevant.
