Already from a distance, passers-by are approaching in irritation. Quite a few of them have tears in their eyes. There are two of these new e-scooters on the pavement, which have recently been seen all over the city. Zero emission, the electric motors whir almost silently. It's more like a beep. Two guys sit cross-legged in front of the scooters, each on a large bag of onions. With great dedication, the two cut the unpopular vegetable into small pieces and pile the onions into a large mountain. Apparatus made of plywood are attached to the rear wheels of the two futuristic machines. The wheels of the electric scooters drive a shaft. On this shaft propellers are mounted, which convert the potential mobility of the vehicles into a steady breeze. The new airstream somehow smells strangely familiar.
