Yeah the front grille of my car remembers.
Traveling from Montreal to Chicoutimi or to Sherbrooke, the car used to be covered in bugs.
Nowadays I don't even have to take it for a wash. I get the odd bug on my windshield and that's it
Probably due to overuse of pesticides.
I've always wondered about this anecdote, partly because I still see a lot of bugs when going out into the country. Is it that there are actually fewer bugs, or do the more aerodynamic cars of today cause fewer dead bugs to stick to bumpers/grills/windshields?

There are fewer bugs.
I've had the same car for 15 years. In that span alone I can confirm there's a lot less bugs on my car.
It's actually the opposite - more aerodynamic means a smaller cushion of air, which should translate to hitting more bugs because they aren't pushed out of the way as strongly or for as long. Instead, insect populations have fallen so dramatically that this effect still doesn't make up for it.
I see this comment so much, but it was never true where I lived. In fact, I only ever experienced the insects covering my windshield thing for the first time less than a decade ago when driving through North Dakota, Montana.... Big, open spaces, I guess. Where I grew up, there were trees and houses everywhere, no real open spaces. So maybe that made the difference.
I just drove through Montana again and had barely half a dozen insects on my windshield throughout the trip, so I do believe that's a very obvious sign for people who live in that kind of area.
Anyway, what I miss is frogs. I used to see frogs and toads and even turtles all the time. Can hardly remember the last time I saw one.
