The one and only time I've been for a trip over a car bonnet was when a car waiting at a give way line pulled out in front of me. I had my front light on the fork leg at that time, and it occurs that the tyre and rim might have gone some way to obscuring his view of it, so I moved it up onto the bars. (Some years later I realised that my map holder might now be obscuring it from anyone high up in a lorry cab.)
