While saving resources, self-help car washes have been used as a sport for exercise, and 24-hour services have been built in urban planning in developed regions of europe for community-based self-help shopping and easy-to-use equipment for self-washers. Self-service chargers, self-recycling, etc., as they are part of public service projects. So not for profit. The prices of goods and services were very low and had ended in 2014. There's something like that on the market. However, small-scale start-ups are the main providers of services, mainly car washers, self-help shopping machines, advertising media machines, and the current situation in the country, where the market for car washes is expanding as more and more people join the race. Etcc (electronictoll colletion clear) has been operating since early 2018 with an innovative self-help car wash model, with more than 1,000 shops in 30 provinces and municipalities throughout the country, an integrated platform for online car services built by registered users of 2 million plus etcc, providing shop owners with a platform for cooperation in online commerce and offline car services. Local car service companies are involved in 4s shops, car finance, car inspection, insurance, maintenance, etc. The project combines smart parking with the self-help car wash project prevailing in the south. A fee management system, developed through self-help, closes the whole car wash, is paid through mobile phones and is open 24 hours to the owner. They come and wash at any time, so as to be quick, time-efficient and economical. This is a response to the cold weather in northern cities and an increase in the experience of car washes. There are now three direct-account shops in the country, more than 1,000 in more than 30 provinces and municipalities throughout the country, and they are growing rapidly at an average of 20 per month. The etcc online comptoir and local car service cooperation platform has been very successful through the sticky nature of daily car washes.
