The Easter Goodwood meeting emphasised once again the difficulties of Grand Prix driving in rain. The three main troubles seem to be altering of engine tune, the slipperiness of the course, and the bad visibility, caused by water on goggles or visor. Of these, the last seems to be the most troublesome and dangerous, yet I have not heard of any driver using the remedy employed by air-lines. A special liquid is sprayed on windscreen or goggles and, without itself affecting visibility, it disperses rain that hits it at speed by breaking up the raindrops into minute particles, which either spray off or are too insignificant to matter. Its inventors claim that a visibility of a few hundred yards is increased to over two miles in the air, so any G. P. driver using it in rain, whether goggles or visor, would gain all immediate advantage over his rivals. No more need for dangerous one-handed driving while mopping goggles with a bit of sponge, or even, in desperation, tearing goggles right off as de Graffenried did at Goodwood.
