It strikes me that speeding in HK is a bargain! Minimum fine in the UK is £100. ( $965)
Sounds like I'm in a minority but having got used to it I generally find HK driving far less stressful than London... Other than for the cross harbour tunnel the traffic is rarely that bad, there's a great deal of tolerance for going slowly if you're a bit lost or trying to work out which of 5 available versions of turning left your sat nav means, and for the most part sticking an indicator on results in a gap opening up even if you're cutting in line. Definitely stark contrast to the much more "competitive" nature of UK city road attitudes.
Probably also helps that I'm in a squishy automatic little SUV rather than the string of silly little sports cars I had in London, but still I think it's pretty logical and easy once you get a view of the main routes in your head.
