Sometimes I wonder about that. The measure is number of insect impacts on windshields but is the car the same?

If we use a more modern care would the increased aerodynamics prevent impacts as instead of punching through the air you are cutting through it?

Have never read the full experimental setup and assumptions... I do know that I have less dead bug then when I was a kid...

Ever since I started riding a motorcycle I've started to believe this to be the case too. I get so many bug splats on my helmet, jacket, and motorcycle that I'd never have if I was driving a car. By the end of most rides out in the country on the highway I'm covered in splats.

i've noted less bugs on the windshield but about the same on the optics and the radiator screen, so i go with the aerodynamics explanation as well. bugs are there because i see the bug swarms around the road too.
