Blinded by oncoming bike path traffic.

As technology advances, brighter lights will become available at yet lower prices.

When people buy lights, they don't really know what features they want; but light output can be easily compared. So a 500-lumen light will likely outsell a 300-lumen light for the same price. No manufacturer will sell more lights by saying their product _doesn't_ blind oncoming traffic.

At some point, we have more megapixels on a camera sensor than we need, more blades on a razor cartridge than we need, and way more cogs on a rear cluster than we need. People will soon be riding around with thousand-lumen lights on the fronts of their bikes. Welcome to the future.
