Co-workers have commented that they detected my R1 headlights at least 1/4 mile in their rear view mirrors, due to the brightness and unique shape of the R1 lenses. Another guy concurred with that observation yesterday in mid-afternoon sunlight. I agreed. If boneheads are busy picking their noses, talk on cellphones, or waxing their lips, they will not see you or even another car. :iamwithst
