If you are aiming your bicycle lights 100 yards in front of you, you are wasting your time, money and batter power. Even Automobile (low beams) aren't aimed 100 yards in front of the vehicle.
Even if your lights are 100 yards ahead of your bicycle, you won't be blinding drivers unless you are riding on the center line. I, personally, don't spend a lot of time there when riding at night because I like my 3rd dimension.
