Car sharing is actually a good idea. People take off their own car and prefer to share one with others. The vehicle is used more frequently and does not stand around for many hours a day. This saves resources and even helps the environment because fewer cars need to be built and fewer parking spaces are necessary. And at best, users save money because they only pay if they drive by car. Depending on the invoice, the abolition of your own car is worthwhile for annual performance of less than 7,000 or less than 12,500 kilometers. This almost corresponds to the average annual mileage of Germans.
