Maybe this question should also request the responder's general location, because I imagine the situations vary substantially.
I've lived in California for most of my life, and we go on frequent drives between LA and SF, usually a few times a year.
In the 80's and 90's bugs would cover the front of our vehicles and the windshield would be difficult to see through even with wipers and washer fluid. We'd actually have to stop to manually scrape them off.
In the 00's and 10's we noticed that we'd get basically zero bugs on a long drive, and that sparked many conversations about California environmental law.
I just got back from a drive up the coast and I can happily say that we're back to insane numbers of bug strikes on the highway. Just north of Ventura I drove through a cloud of large bugs that hit like rocks and instantly covered almost my entire windshield. This situation has been noticably turning around since COVID, which I think is a good thing
