Something else I thought of that's been handy over the years. Rather than having to stop if a bug has died on your visor, right in your eyeline, as they always do. If you place a piece of double sided tape on the top of an old aerosol lid, not the ones with the little hole in, and stick it to your left hand infil out of the airstream. Chop a piece off the shammy you leather the car off with, add water, sorted. No time lost wiping crap off your visor.
