I've used both MRT in Singapore and MTR in Hong Kong extensively and it's simply the future. Individually owned transit vehicles only makes sense in rural areas where there are no options. In larger cities, the only thing that makes sense is public transport. The externalities of individual car ownership creates so many negative factors in a cramped city environment that I'm convinced we'll look back at it and laugh in a hundred years. There won't be individual car ownership (except for collectors) because noone will want the liability when comparing it to the options.
