I can aim my helmet light at a driver's eyes, and I have, but that's only when they are doing something stupid that could get me squished.
Most cyclists I meet at night are aiming their lights in a similar fashion.
I can honestly say I've never had a problem being noticed with my Cateye Double Shot, or even a 10w halogen for that matter. The idea that you need over 300 lumens to be noticed by cars is a bit far fetched.
