This term describes the noticeable decline in dead bugs accumulating on front glass and grilles during long highway drives. Drivers and mechanics use this concept to discuss broader environmental changes in insect populations. Aerodynamic improvements in vehicle design also play a role by directing airflow smoothly over the car rather than squarely into it.

Insider tip
While often cited as purely an ecological issue, the shift from boxy front ends to sleek, wind-tunnel-tested shapes significantly reduces the impact rate of airborne insects.
