Driving to the car wash is a waste of time and effort.
Today’s invention is a mobile carwash that comes to your car. A small vehicle drives down the pavement and extends its brushed arms around your car as shown.
The operator would decide how dirty each car was and use only enough water and detergent to deal with the job in hand.
In this way, an entire street of parked cars could be washed very economically, whilst their owners were elsewhere.
