On my travels through Hong Kong, I stood there admiring a particular sign on the street.
Basically, it's a city warning sign.....a cop can ticket and prosecute you....without any warning.....if you were waiting. It could be a minute of waiting....it could be 8 seconds of waiting....it doesn't matter.
Generally, I'd be a bit scared of city driving there. A cop could nicely tap on my window, and suddenly for some stopping phase of five seconds.....I'd be called into court and prosecuted for something.
