Just another data point to add: exactly the same thing has happened here in Australia. The family used to regularly drive 2000km on holidays. Dead bugs covered the windshield and radiator at the end of each leg. Today with cheap plane fares we don't drive so much, but I still do a one 1000km drive every 5 years or so. I don't recall washing a single bug off whereas when I was a kid scraping dried bug guts was a major chore. 76% sounds almost too low, but I suspect the the biggest bugs are the hardest hit and they caused the mess on the car. I don't remember when I last saw a locust. They used to be a major problem. We used to have surfaces carpeted in beetles during their breeding season, and yet this Christmas I was actually surprised when I saw a Christmas beetle.
