I can't attest to their results but the producers of the super-aerodynamic aptera claim that almost no bugs wind up on the aptera as compared to their chase car, because the bugs wind up unharmed through the slipstream. Though I believe that there is likely an broad insect decline, for the bug splat anecdotes (remembering that the plural of anecdote is data) we also can't rule out that bugs are evolving based on selective pressure to avoid thoroughfares.
