1. Context

You are developing a new Wash-Wipe system to be used in a range of medium to large passenger cars including a saloon, an estate, a jeep and a cabriolet version. The cars will be sold all over the world including regions such as Scandinavia, mainland Europe, the Arabian Gulf, and South-East Asia. The environment in these regions includes arctic (winter temperatures down to −40° C), desert (summer temperatures up to 50° C; winter sandstorms), and monsoon (100% humidity; temperatures up to 35° C; precipitation up to 50 mm/hour) climates. Both left- and right-hand drive versions are required to cater for the countries involved. The jeep and the estate will be used on- and off-road, are subjected to intense vibration off-road, and may become very muddy. In all the versions, driver comfort and simplicity of operation have high priority, second only to safety.
