@m1ckDELTA , I really liked this question, growing up around touchless carwashes had me assuming it was normal everywhere and used for any vehicle. Your curiosity triggered my curiosity and reminds me how it has been a interesting journey in appreciating and enjoying my Royal Enfield. It turns out, at least 5 years ago, you couldn't just drive around until you find the local car wash stalls, and when you do find a car wash, it is a person. I don't know if touchless car wash stations or bays have become more available, but they don't appear to be if people living abroad in India who post about missing them is any indication. I found this Forbes article from 5 years ago whose video shows people washing their own cars (for those who can afford them) with a 5 gallon bucket of water and is an advertisement for a steam cleaning alternative which uses and wastes less water and is more hygienic as its benefits.
India's water woes, dengue health concerns, and lack of car washing facilities got entrepreneur Chirag Shah thinking – what if he started washing cars for a living, but not in the traditional way?

One part of the RE journey for me has been seeing and appreciating what the real differences and constraints are that lead them to engineering solutions as they do.
