+1 This ^^^^ Most drivers don't speed towards bright lights! In fact, instinct would dictate just the opposite reaction. As soon as you're faced with a bright light, you instinctively hit the brake. How hard you hit the brake is usually determined by both the degree of brightness and the speed at which it approaches. Either the light source appears to get larger, become brighter, or both.

The only problem there is, the light being so bright as to become blinding, and actually becoming a hazard to road safety.

I guess the question becomes:

At what point does bright light, become too bright to maintain safe transport for all?
