“Many people have noticed this, and it isn’t just nostalgia. The main reasons are a mix of fewer insects and changes in cars and driving.
1. Insect populations really have declined
This is the biggest factor. Long-term studies in Europe and North America show large drops (often 40–75%) in flying insect biomass over recent decades. Key causes include:
- Intensive agriculture (pesticides, especially neonicotinoids)
- Loss of habitat (hedgerows, wildflower meadows, wetlands)
- Light pollution disrupting insect behavior
- Climate change, which alters life cycles and food sources
Fewer insects in the environment means fewer to hit windscreens.
2. Modern cars are more aerodynamic
Older cars were boxier, with upright windscreens that insects hit directly. Newer cars:
- Have sloped windscreens
- Channel airflow up and over the car
This airflow can carry insects over the roof instead of splattering them on the glass.
3. Changes in driving patterns
More people drive on motorways rather than rural roads
- Cars are better sealed, quieter, and smoother, so impacts are less noticeable
- Seasonal driving habits (air-conditioning instead of open windows) reduce awareness
4. Cleaner roadsides
Road verges used to be rich in wildflowers and insects. Many are now:
- Regularly mown
- Treated with herbicides
This removes food and breeding space right where cars pass.
5. Windscreen technology
Modern glass, coatings, and washer systems can make insect impacts less sticky or more easily dispersed, so they’re less obvious.”
Or it could be a government conspiracy
