It’s two things, one personal vehicles are designed to bend air around them rather than slice through or just brute force through air resistance. This means that more bugs are pushed out of the way with newer vehicles now, compared to older vehicles which just had the bug hit the windshield. The second and much more impactful reason is because the insect population has dropped significantly in the last 25 years.
what happened to the bugs?
It’s two things, one personal vehicles are designed to bend air around them rather than slice through or just brute force through air resistance. This means that more bugs are pushed out of the way with newer vehicles now, compared to older vehicles which just had the bug hit the windshield. The second and much more impactful reason is because the insect population has dropped significantly in the last 25 years.
Why has that happened?
Pesticides
Climate change
Less flowers
Accelerating climate change and an increase in consumer car culture (more cars on road to kill bugs = less bugs)
We managed to kill off a third of the entire bug population during the last 25 years or so.
