From the size of the pattern mentioned above, the pics on the website seem to be pretty optimistic.
I also think if you're going slow enough for that to be of use, you may as well be walking. Will be interesting to see this when it's being used in the Real World. I could also imagine this causing one to watch nothing but the grid and becoming another scratch on a parked car's bumper. I don't know ... wheel chair use maybe?
