It depends where in the UK you are driving, I have to wash the car after every major journey > 1hr long because its covered in dead insects and the red, I guess blood, staining the paint. I would say there has been more sightings of wildlife and more insects this year because of lockdown, more hedgehogs seen walking on the roads, more deer, rabbits and plenty of insects especially at night at the moment. So I normally walk my dog with a headtorch at night as its cooler for him to run around off the lead but the insects getting attracted to my headtorch this year is a stupid amount to the point I've stopped taking him out at night. Germany may be onto something by reducing the light sources. Where I live we do have LED street lamps which cast a very definite circle of light on the road, but there is no "side leakage" of light so its darker walking between street lamps. You also dont get any orange glow into your house or bedroom window like the old style street lamps used to do which can keep you awake especially when stressed. The number of small birds nesting in the area has also gone up over the last two years but its nice watching them feeding on insects crawling up and down plants like rose bushes, or hanging onto the side of brick houses getting the odd bug.
