Yes - I actually just signed up for it myself. I saw none in South Lantau (two in Tung Chung, I guess you could always message them and ask!). But there are many cars in other places, eventually someone in South Lantau will sign up! Or you could buy a car, get the permit and rent it out yourself for the 90% of the time you don't need it! It seemed all of the reasonably priced cars were being rented every weekend judging from the date of each review....
