You clearly don’t understand light diffusion then.
If your light bulb is say 10cm², and all mostly pointing forward through a 100cm² clear plastic or glass like a laser, then the oncoming driver is basically either looking at a laser, or looking away.
But if you evenly diffuse that 10cm² light through the 100cm² lens, then the light is much more even and smooth, equal lighting from the same light, gives good vision to the driver, and doesn’t blind oncoming drivers.
Edit: Yes I just pulled simple numbers out of my ass for simplicity, but the basic fact holds true, that if all the lumens point one way, they’re gonna blind oncoming drivers.
But if you diffuse that same light energy evenly across a good broad angle range (let’s say around 60⁰ or so), then the light illuminates evenly, and isn’t like shining a laser light at an airplane…
Also, just a friendly reminder, it’s illegal to shine lasers at aircraft, so why would anyone support or approve of that on the roads?
