And visibility is relative. A 'flood' will also be more visible over a wider angle to oncoming traffic, simply because the light source will be less focused. That actually provides better day-time visibility and night-time visibility thats OK for a cyclist. Lights are usually a supplement to street lighting and unless you're in an unlit area, are more critical to being seen than for lighting up the road.
That's fine if you are keeping your eyes on the road all the time, but when there is traffic, I might look away for a couple of seconds, or look behind me. I don't want to look back on the road to find that I have to make a quick stop or maneuver around something in the road.
