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.
fluid dynamics simulated on computers helped air-bending, that's cool. i knew about the bees disappearing, but bugs in general too?
Unfortunately yes. This story by NPR isn't an academic source but it's definitely worth listening to. On average bug populations have declined by 2% a year for decades or more in some areas, less in others. It's an average.
Now truthfully, whether or not a declining bug population is the main cause of fewer bugs on our windshields or if it's better aerodynamics I don't know. What I do know is a more aerodynamic vehicle isn't something I need to worry about, a declining bug population is.
we need our bugs! although I was never convinced in that all insectizoid parasites are necessary, like any that affect Me, or Me-Kind
