Hard to make that argument in broad daylight though, because there's a lot more to see, including the rider on the bike, to help better judge distances.
Bright lights, especially at any distance, tend to mask details near them.
The eye is naturally drawn to the bright light, especially if somebody is only
taking a quick glance. They'll see the light, know something is there, but
will likely be unable to distinguish the details of the object allowing finer
interpretation - like speed. Bigger objects are easier.
