UK here. It's just not a thing any more. I regularly drive - or am a passenger - on a ~200 mile round trip and insect strikes just don't happen.
That said, I recently drove from the North of England to the South of France. Almost as soon as we crossed the Channel we were instantly getting insects splattered on the windscreen to the point we had to refill buy some bright pink no-nonsense washer fluid at the next services. So I assume some counties are more responsible than others with their use of pesticides.
If the cable coming through the wall is coaxial like the pictire OP posted, that's exactly what's happening. New installs will be FTTP and a lot of networks have been upgraded, but there's still plenty of areas using DOCSIS over coax.
