While this claim is plausible, it’s (admittedly pleasing) conjecture until you provide evidence.

I saw it myself, we did high speed off-roading and smashed a ton of bugs. But on the highway? Little to no bugs.

That doesn't prove anything. Disturbing burrowing bugs or bugs in grass and bushes with rumbling and lights is easily enough to account for a vast difference alone...Then consider the environment was more wild with more habitat space for bugs compared to a road...
