Stop blaming roads on consumer trucks. Nearly all the damage is 18 wheelers.

No where did I mention that the cause of road damage was caused by SUVs. I said that people prefer larger vehicles because they driver better on poorly maintained roads due to larger tires and heavy duty suspension.

Also, 18 wheelers don’t drive in residential areas and therefore don’t affect most smaller roads. Those roads fall apart due to a variety if reasons including weather and lack of maintenance and drainage.

As for your other claim, there is plenty of evidence that LED headlights are brighter. This is easily measurable and new headlights have higher lumens and a different color. Newer cars all have LED lights that are more blue than older halogen lights that were yellow.

Trucks and SUVs have gotten bigger and taller over the last 2-3 decades and those headlights are at eye level for most cars. This causes more glare and when combined with brighter LED lights that have a blue color balance lead to glare!

US laws around headlights have not been updated since the 1970s! European laws are also more strict on aiming downward to reduce glare from trucks and tall vehicles.

Since you want some proof:
