I'm guessing that most GPS receivers give us about 10 meter (30 feet) accuracy. How could it possibly benefit a driver to have a GPS receiver with accuracy better than that if just in one second we pass distance much greater than that?

Makes sense to me. You just need to be in the ballpark, not down to the foot.
