In fact, I've only seen one gas station in my whole time being here, so it would be rather inconvenient to drive too far. There are also many ferries to take, if you'd like to go to an island that is connected to other places by a bridge.
It only took me about a week of staying in Hong Kong until I felt comfortable taking the M.T.R. alone. The stations themselves are very clean, and trains usually arrive every three to six minutes, so there's never a rush to catch one. There are also lots of maps around the stations and on the trains themselves to figure out your route. The intercom on the train regularly announces which station the train is approaching, as well as whether or not the station is an interchange station to get on to a different line. Even if you miss your stop, it is fairly easy to hop on a train back to where you need to go, free of charge.
I have only taken the minibuses and double-deckers a handful of times, but it is always an experience. You use them to get to places in Hong Kong that are not so lucky as to be right by a station. While the buses come to regular stops every 20 minutes to every hour, they also stop at lots of villages and other spots more off the beaten path. They can stop pretty fast, though, and there have been a couple of times I have found myself bouncing off the walls of a double-decker while trying to hustle my way off the bus. Even when the language barrier is more prominent on these forms of transportation, I usually can still manage to figure out which stop is mine. I never feel like I will get truly lost.
