The MTR in Hong Kong in fabulous.
It is used by so many people that the trains run every few minutes which make getting around the city so easy. We have used the public transport every day and feel more and more confident every time we enter a new stations. Also because this form of transport is so popular, the prices are amazingly cheap. In Perth, travelling 3 or 4 stops up the line costs me nearly $4, which doesn't really encourage use. The regularity of trains in incredible too. If you miss one, you really only need to wait for about 3 minutes.
Each of us has an Octopus card and this has allowed us to jump on and off trains, trams and ferries easily.
We even managed to get up The Peak and across to Kowloon using these cards.
I can't really see the need for a car with system that works this well.
P.S. To those bloggers who I regularly read, I will get back to stopping by to your blogs as soon as I have more regular internet access. I am looking forward to catching up with everything you have been doing in a few weeks.
