Discovery Bay as we know is a unique enclave in Hong Kong. It's all privately built; even the police and fire stations. Private cars are banned and access is either by ferry, or by public transport via a 2.3-kilometre land tunnel. There is a small police presence and a fire station with three fire engines.
But one of the curiosities of the way the tunnel operates is that police and other emergency service vehicles are required to pay a toll when they pass through the tunnel. This is because it's a private tunnel. Indeed this is true for all private tunnels in Hong Kong.
You would have thought that given the nature of the work of the emergency services, they would be exempt from paying tolls. It's a public good. They don't have to pay up on the spot, but the tunnel company sends the government a monthly bill. In the case of the Discovery Bay Tunnel it's HK$50 a time.
It seems strange that the government didn't insist that emergency vehicles should be toll free. Fortunately the emergency services don't adopt an entrepreneurial approach to dealing with fires, for example.
Elections around the world have been changed with the introduction of e-mail and social media. Candidates are keen on sending out their message using these platforms as they feel they can get "closer" to people.
