From John Corey, Melrose, New York, US
Your report states that bug splats on UK cars declined by 58 per cent per car-mile travelled between 2004 and 2021, and suggests that this was due to declining bug numbers (14 May, p 23). Would it not also be dependent on traffic density? That is, if the number of car-miles driven had doubled, in a world with constant bug levels, then the splat count per car would surely fall by nearly as much.
