How slow do you have to be going to be staring at the contours 10 feet in front of your bike? Yes, I want some illumination there, but my typical speeds are 15 to 30 MPH with a 19 MPH average. By the time a pothole is as close to my bike as it is in that photo, I probably can't avoid it. I need lighting that goes 50 feet in front of me at least.

Also, that doesn't replace lighting, it would only supplement it. Wouldn't the conventional lighting mostly wash out the grid?
