Yes it is. About half of the worlds population lives just on the poverty side of being able to afford the luxuries of indoor plumbing, clean water, and refrigeration. Most of the world doesn't have mail delivered to their doorstep ether.

I have read that maybe half of the aprox. one billion bicycles in use today are push-bikes. Used for carrying loads of food, fuel, water.

I am a sport/hobbyist cyclist myself. And I truly appreciate my undeserved good fortune.

I thought the conclusions were pretty straight forward: Only a small number of nighttime accidents can be clearly attributed to the lack of lights: Other major risk factors are driving or riding under the influence of alcohol, high- er driving speeds on empty roads at night and impaired night vision especially in older drivers....

IMHO: Bicycling while drinking and/or drugging is comparative to drinking and driving. It's not a big killer.... it is by far THE big killer. Cyclist always divert the conversation about cycling deaths to paths, road conditions, separated lanes, reflective clothing... and bicycle lights. When the big killer is and always has been booze and drugs.
